Spring

Question

具体例外是：

Failed to instantiate [org.springframework.context.annotation.AnnotationConfigApplicationContext]: Constructor threw exception;
nested exception is org.springframework.context.annotation.ConflictingBeanDefinitionException:
Annotation-specified bean name 'myService' for bean class [my.package.ejb.MyService] conflicts with existing, non-compatible bean definition of same name and class [my.package.other.ejb.MyService]

那些 MyService 接口甚至没有注释，它们代表 EJB 2.0 无状态 bean。

我的注解配置如下

@Configuration
@ComponentScan("my.package")
@MapperScan("my.package")
public class ApplicationConfiguration {
    @Bean
    public DataSource dataSource() {
        return new JndiDataSourceLookup().getDataSource("...");
    }

    @Bean
    public SqlSessionFactoryBean sqlSessionFactory(final DataSource dataSource) {
        final SqlSessionFactoryBean sqlSessionFactory = new SqlSessionFactoryBean();
        sqlSessionFactory.setDataSource(dataSource);
        sqlSessionFactory.setConfigLocation(new ClassPathResource("..."));
        return sqlSessionFactory;
    }

    @Bean
    public DataSourceTransactionManager dataSourceTransactionManager(final DataSource dataSource) {
        return new DataSourceTransactionManager(dataSource);
    }
}

可能与 @MapperScan（来自 MyBatis）和 @ComponentScan 不兼容？

异常来自 SpringBeanAutowiringInterceptor 我用来自动装配 EJB 3.0 字段。

Answer 1

MapperScannerConfigurer 的文档说：

This class supports filtering the mappers created by either specifying a marker interface or an annotation. The annotationClass property specifies an annotation to search for. The markerInterface property specifies a parent interface to search for. If both properties are specified, mappers are added for interfaces that match either criteria. By default, these two properties are null, so all interfaces in the given basePackage are added as mappers.

基本上我将数千个接口映射为 bean。不酷！
伙计们，我的错。

Spring - 与现有的、不兼容的同名 bean 定义和 class 冲突

Spring - conflicts with existing, non-compatible bean definition of same name and class

autowired
