关于使用spring版本4.1.6注解@Import报错
记录一下遇到的错误 org.springframework.beans.factory.parsing.BeanDefinitionParsingException:
使用环境:spring 4.1.6
代码:
类1 配置类
@Configuration
@Import(value= {Sky.class,MyImportSelector.class})
public class MainConfig3 {
}
类2
public class MyImportSelector implements ImportSelector {
public String[] selectImports(AnnotationMetadata importingClassMetadata) {
// String className = importingClassMetadata.getClassName();
// System.out.println(className);
return new String [] {"com.leon.pojo.Dog","com.leon.pojo.Sky","com.leon.pojo.Bird"};
}
}
类3 测试类
public class MainTest {
AnnotationConfigApplicationContext config = new AnnotationConfigApplicationContext(MainConfig3.class);
@Test
public void testImport() {
String[] names = config.getBeanDefinitionNames();
for(String st : names) {
System.out.println(st);
}
}
很简单的一个导入bean注解,测试代码
在使用import的时候报错:
org.springframework.beans.factory.parsing.BeanDefinitionParsingException:
Configuration problem: com.leon.pojo.Sky was @Import'ed but is not annotated with @Configuration nor does it declare any @Bean methods; it does not implement ImportSelector or extend ImportBeanDefinitionRegistrar. Update the class to meet one of these requirements or do not attempt to @Import it.
Offending resource: class com.leon.pojo.Sky
解决方案:
1.在导入的bean类上加上@Repository 这样就能正常使用
2.把版本升级到4.2.6 (测试可用) 或者更高
