Springboot No qualifying bean of type [javax.sql.DataSource]

I’m trying to use application.properties to bean datasource but it seems that spring boot does not find the file or something like.

Caused by: org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type [javax.sql.DataSource] found for dependency: expected at least 1 bean which qualifies as autowire candidate for this dependency. Dependency annotations: {}

Here my structure:

. ├── build.gradle └── src └── main ├── java │ └── com │ └── companies │ ├── CompanyApplication.java │ ├── config │ │ └── WebMvcConfig.java │ ├── controller │ │ └── HelloWorldController.java │ └── model │ ├── Article.java │ ├── daoInterface │ │ └── ArticleDaoInterface.java │ ├── daoTemplates │ │ └── ArticleDao.java │ └── mappers │ └── ArticleMapper.java ├── resources │ └── application.properties └── webapp └── WEB-INF └── pages └── hello.jsp

I’ve try to move application.properties file from resources to config and nothing. application.properties:

spring.datasource.driver-class-name=com.mysql.jdbc.Driver spring.datasource.url=jdbc:mysql://127.0.0.1:3306/name spring.datasource.username=root spring.datasource.password=root spring.datasource.driver-class-name=com.mysql.jdbc.Driver

build.gradle

buildscript { repositories { //Required repos mavenCentral() maven { url “http://repo.spring.io/snapshot” } maven { url “http://repo.spring.io/milestone” } } dependencies { //Required dependency for spring-boot plugin classpath “org.springframework.boot:spring-boot-gradle-plugin:1.2.6.RELEASE” } } apply plugin: ‘java’ apply plugin: ‘war’ apply plugin: ‘spring-boot’ jar { baseName = ‘companies’ version = ‘0.2’ } war { baseName = ‘companies’ version = ‘0.1’ } sourceCompatibility = 1.8 targetCompatibility = 1.8 repositories { mavenCentral() maven { url “http://repo.spring.io/snapshot” } maven { url “http://repo.spring.io/milestone” } } dependencies { compile ‘org.springframework.boot:spring-boot-starter-web’ compile(“org.springframework.boot:spring-boot-starter”) compile(“org.springframework:spring-jdbc”) compile(‘org.springframework.boot:spring-boot-starter-jdbc:1.2.6.RELEASE’) testCompile(“junit:junit”) //Required dependency for JSP compile ‘org.apache.tomcat.embed:tomcat-embed-jasper’ }

And where I’m trying to autowire the dataSource:

package com.companies.model.daoTemplates; import com.companies.model.Article; import com.companies.model.daoInterface.ArticleDaoInterface; import com.companies.model.mappers.ArticleMapper; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.jdbc.core.JdbcTemplate; import org.springframework.stereotype.Repository; import javax.sql.DataSource; import java.util.List; @Repository public class ArticleDao implements ArticleDaoInterface { private JdbcTemplate jdbcTemplateObject; private final String DB_NAME = “articles”; @Override @Autowired public void setDataSource(DataSource ds) { this.jdbcTemplateObject = new JdbcTemplate(ds); } @Override public List

listArticle() { String SQL = “select * from ” + DB_NAME + ” where inactive = false ORDER BY name”; List

article = jdbcTemplateObject.query(SQL, new ArticleMapper()); return article; } }

CompanyApplication.java

package com.companies; import org.springframework.boot.SpringApplication; import org.springframework.boot.autoconfigure.EnableAutoConfiguration; import org.springframework.context.annotation.ComponentScan; import org.springframework.context.annotation.Configuration; @Configuration @ComponentScan @EnableAutoConfiguration public class CompanyApplication { public static void main(String[] args) { SpringApplication.run(CompanyApplication.class, args); } }

I cannot find where I’m failing at.

No qualifying bean of type ‘javax.sql.DataSource‘ available: expected at least 1

The startup class has been configured

@SpringBootApplication(exclude = {DataSourceAutoConfiguration.class})

The error information is as follows:

org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name ‘org.springframework.boot.autoconfigure.orm.jpa.HibernateJpaAutoConfiguration’: Unsatisfied dependency expressed through field ‘dataSource’; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type ‘javax.sql.DataSource’ available: expected at least 1 bean which qualifies as autowire candidate.

Dependency annotations: {@org.springframework.beans.factory.annotation.Autowired(required=true)}

Reason: the default datasource is used.

solution: start the accumulation configuration

Issue

I am using spring mvc version 5.

I am struggling in an autowire problem. I am following a spring security JDBC tutorial. Here is the AppConfiguration.class :

package com.blog.configuration; import javax.sql.DataSource; import org.apache.commons.dbcp2.BasicDataSource; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.context.annotation.Bean; import org.springframework.context.annotation.ComponentScan; import org.springframework.context.annotation.Configuration; import org.springframework.context.annotation.PropertySource; import org.springframework.core.Ordered; import org.springframework.core.env.Environment; import org.springframework.web.servlet.config.annotation.EnableWebMvc; import org.springframework.web.servlet.config.annotation.WebMvcConfigurer; import org.springframework.web.servlet.config.annotation.ResourceHandlerRegistry; import org.springframework.web.servlet.config.annotation.ViewControllerRegistry; import org.springframework.web.servlet.view.InternalResourceViewResolver; import org.springframework.web.servlet.view.JstlView; @Configuration @EnableWebMvc @ComponentScan({ “com.blog” }) @PropertySource(“classpath:db.properties”) public class AppConfiguration implements WebMvcConfigurer { @Autowired private Environment env; @Bean public InternalResourceViewResolver viewResolver() { InternalResourceViewResolver viewResolver = new InternalResourceViewResolver(); viewResolver.setViewClass(JstlView.class); viewResolver.setPrefix(“/WEB-INF/views/”); viewResolver.setSuffix(“.jsp”); return viewResolver; } /** * Configure ResourceHandlers to serve static resources like CSS/ Javascript * etc… */ public void addResourceHandlers(ResourceHandlerRegistry registry) { registry.addResourceHandler(“/resources/**”).addResourceLocations(“/resources/”); } /** * configure spring security custom login page */ @Override public void addViewControllers(ViewControllerRegistry registry) { registry.addViewController(“/login”).setViewName(“login-page”); registry.setOrder(Ordered.HIGHEST_PRECEDENCE); } @Bean public DataSource dataSource() { BasicDataSource dataSource = new BasicDataSource(); dataSource.setDriverClassName(env.getProperty(“mysql.driver”)); dataSource.setUrl(env.getProperty(“mysql.jdbcUrl”)); dataSource.setUsername(env.getProperty(“mysql.username”)); dataSource.setPassword(env.getProperty(“mysql.password”)); return dataSource; } }

and here is the SecurityConfig.class :

package com.blog.configuration; import javax.sql.DataSource; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.context.annotation.Bean; import org.springframework.security.config.annotation.authentication.builders.AuthenticationManagerBuilder; import org.springframework.security.config.annotation.web.builders.HttpSecurity; import org.springframework.security.config.annotation.web.configuration.EnableWebSecurity; import org.springframework.security.config.annotation.web.configuration.WebSecurityConfigurerAdapter; import org.springframework.security.crypto.bcrypt.BCryptPasswordEncoder; import org.springframework.security.crypto.password.PasswordEncoder; @EnableWebSecurity public class SecurityConfig extends WebSecurityConfigurerAdapter { @Autowired private DataSource dataSource; @Autowired PasswordEncoder passwordEncoder; @Override protected void configure(AuthenticationManagerBuilder auth) throws Exception { auth.jdbcAuthentication().dataSource(dataSource) .usersByUsernameQuery(“select username, password, enabled” + ” from users where username=?”) .authoritiesByUsernameQuery(“select username, authority ” + “from authorities where username=?”) .passwordEncoder(new BCryptPasswordEncoder()); } @Bean public PasswordEncoder passwordEncoder() { return new BCryptPasswordEncoder(); } @Override protected void configure(HttpSecurity http) throws Exception { http.authorizeRequests().antMatchers(“/”).permitAll().antMatchers(“/resources/**”).permitAll() .antMatchers(“/admin/**”).hasRole(“ADMIN”).and().formLogin().loginPage(“/login”).permitAll(); } }

and the pom.xml :

The dataSource autowiring is not working, I don’t know why. It gives me error: No qualifying bean of type ‘javax.sql.DataSource’ available. What is the problem?

Solution

Move your bean creation code to root configuration class ( SecurityConfiguration in your case.)

@Bean public DataSource dataSource() { BasicDataSource dataSource = new BasicDataSource(); dataSource.setDriverClassName(env.getProperty(“mysql.driver”)); dataSource.setUrl(env.getProperty(“mysql.jdbcUrl”)); dataSource.setUsername(env.getProperty(“mysql.username”)); dataSource.setPassword(env.getProperty(“mysql.password”)); return dataSource; }

Move above code to root configuration.

Because beans defined in servlet context is not visible in root/application context as root context is initialized first and then servlet context.

If you define bean in root context you can use(autowire) it in servlet context.

What is mean by root-context and servlet-context

Root context —— Context’s Loaded by ContextLoaderListener

Servlet context — Context’s Loaded by DispatcherServlet

If you want to know what is rootContext and what is servletContext and also to have clear idea about accessing beans between context Refer my answer from this link

org.springframework.boot spring-boot-autoconfigure

Spring will rely on the spring-boot-autoconfigure

jar package. There is a DataSourceAutoConfiguration in this jar package that will initialize the DataSourceInitializer class. This class has an init method to get the DataSource (data source)

@Configuration @ConditionalOnClass({ DataSource.class, EmbeddedDatabaseType.class }) @EnableConfigurationProperties(DataSourceProperties.class) @Import({ Registrar.class, DataSourcePoolMetadataProvidersConfiguration.class }) public class DataSourceAutoConfiguration { @Configuration @ConditionalOnMissingBean(DataSourceInitializer.class) protected static class DataSourceInitializerConfiguration { @Bean public DataSourceInitializer dataSourceInitializer() { return new DataSourceInitializer(); }

In the initialization method, the data source needs to be initialized. Some ddl operations are also used in the runSchemaScripts() method to check whether sql script needs to be executed during initialization. When you have two data sources, the program does not know which one to use, so an error is reported

@PostConstruct public void init() { if (!this.properties.isInitialize()) { logger.debug(“Initialization disabled (not running DDL scripts)”); return; } if (this.applicationContext.getBeanNamesForType(DataSource.class, false, false).length > 0) { this.dataSource = this.applicationContext.getBean(DataSource.class); } if (this.dataSource == null) { logger.debug(“No DataSource found so not initializing”); return; } runSchemaScripts(); } private void runSchemaScripts() { List scripts = getScripts(this.properties.getSchema(), “schema”); if (!scripts.isEmpty()) { runScripts(scripts); try { this.applicationContext.publishEvent(new DataSourceInitializedEvent( this.dataSource)); //The listener might not be registered yet, so don’t rely on it. if (!this.initialized) { runDataScripts(); this.initialized = true; } } catch (IllegalStateException ex) { logger.warn(“Could not send event to complete DataSource initialization (” + ex.getMessage() + “)”); } } }

Solution:

If it is xml configuration,

add primary=”true” to the place where the data source is defined. Remember to add only one of them. When there are multiple data sources, mark this data source as the main

If it is a spring boot project, the

spring boot startup class plus exclude = DataSourceAutoConfiguration.class means that this class is not loaded when the project is started.

Example:

@ComponentScan(basePackages = “com.pinyu.system”) @MapperScan(“com.pinyu.system.mapper”) @EnableTransactionManagement @SpringBootApplication(exclude={ DataSourceAutoConfiguration.class, //HibernateJpaAutoConfiguration.class,//(if you use Hibernate, you need to add) DataSourceTransactionManagerAutoConfiguration.class, }) public class Application extends SpringBootServletInitializer { }

It depends on what exactly is in there, but if you just make your parent the spring boot starter then it should work

Spring Boot 2 datasource by configuration does not work

I have an application.yml(!) for the configuration containing the following:

spring: datasource: url: “jdbc:h2:file:./camunda-h2-database” driverClassName: “org.h2.Driver” username: “sa” password: “”

Which gives me the errormessage:

2021-03-11T17:02:48,600 WARN [main] o.s.c.s.AbstractApplicationContext: Exception encountered during context initialization – cancelling refresh attempt: org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name ‘org.camunda.bpm.spring.boot.starter.CamundaBpmAutoConfiguration$ProcessEngineConfigurationImplDependingConfiguration’: Unsatisfied dependency expressed through field ‘processEngineConfigurationImpl’; nested exception is org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name ‘processEngineConfigurationImpl’ defined in class path resource [org/camunda/bpm/spring/boot/starter/CamundaBpmConfiguration.class]: Unsatisfied dependency expressed through method ‘processEngineConfigurationImpl’ parameter 0; nested exception is org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name ‘camundaDatasourceConfiguration’: Unsatisfied dependency expressed through field ‘dataSource’; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type ‘javax.sql.DataSource’ available: expected at least 1 bean which qualifies as autowire candidate. Dependency annotations: {@org.springframework.beans.factory.annotation.Autowired(required=true)}

Doing it this way works:

public DriverManagerDataSource dataSource() { DriverManagerDataSource dataSource = new DriverManagerDataSource(); dataSource.setDriverClassName(“org.h2.Driver”); dataSource.setUrl(“jdbc:h2:file:./camunda-h2-database”); dataSource.setUsername(“sa”); dataSource.setPassword(“”); return dataSource; } @Bean public PlatformTransactionManager transactionManager() { return new DataSourceTransactionManager(dataSource()); }

Ideas? 🙂

Answer

Rename driverClassName to driver-class-name since Kebab case is preferred over Camel case in Spring Boot Auto Configuration properties.

If that doesn’t help then make sure that you didn’t turn off DataSourceAutoConfiguration feature. It usually may look like
