Spring Boot JPA找不到数据源

Question

I have a spring boot application with the following configuration:

Application

@SpringBootApplication(exclude = {ErrorMvcAutoConfiguration.class,
        DataSourceAutoConfiguration.class,JpaRepositoriesAutoConfiguration.class})
public class Application extends SpringBootServletInitializer {

Main configuration class:

@Configuration
@ComponentScan("com.mycompany.it")
@Import(DatabaseConfiguration.class)
public class Configuration extends WebMvcConfigurationSupport {

Database configuration:

@Configuration
@ComponentScan(basePackages = {"com.mycompany.it.xp2.integration.workday.dao","com.mycompany.it.xp2.integration.workday.application","com.company.it.xp2.integration.workday.model"})
@EnableAspectJAutoProxy
@EnableTransactionManagement
@EnableJpaRepositories(basePackages = {"com.company.it.xp2.integration.workday.dao","com.company.it.xp2.integration.workday.model"})
public class DatabaseConfiguration {

With DataSource bean declaration:

@Bean(destroyMethod = "close")
    @Primary
    public DataSource dataSource() throws PropertyVetoException {
        ComboPooledDataSource source = new ComboPooledDataSource();
        source.setDriverClass(driverClass);
        source.setJdbcUrl(jdbcUrl);
        source.setUser(jdbcUsername);
        source.setPassword(jdbcPassword);
        source.setInitialPoolSize(initialSize);
        source.setMaxPoolSize(maxActive);
        source.setMinPoolSize(minIdle);
        return source;
    }

However when I start up the application I get the following error:

Caused by: org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'org.springframework.boot.autoconfigure.orm.jpa.HibernateJpaAutoConfiguration': Unsatisfied dependency expressed through constructor parameter 0; 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: {}

Here are the related lines from gradle:

compile group: 'org.springframework.boot', name: 'spring-boot-starter-web'
compile group: 'org.springframework.boot', name: 'spring-boot-starter-actuator'
compile group: 'org.springframework.boot', name: 'spring-boot-starter-aop'
compile group: 'org.springframework', name: 'spring-orm'

compile group: "org.springframework.boot", name: "spring-boot-starter-jdbc"
compile "org.springframework.boot:spring-boot-starter-data-jpa"

Spring boot version 1.5.3

Answer 1

Check the error log

1 bean which qualifies as autowire candidate. Dependency annotations

It seems that there is an error when you configured the bean.
