使用Lombok 进行Spring 注入

spring 注入方式为2种，构造器注入和setter 注入

使用Lombok 进行setter 注入(尽量优先使用setter 注入)

@Service
@Setter(onMethod_ = {@Autowired})
public class TestServiceImpl implements TestService {private TestDao testDao;}

看一下编译的内容

@Service
public class TestServiceImpl implements TestService {private TestDao testDao;@Autowiredpublic void setTestDao(final TestDao testDao) { this.testDao = testDao;}}

使用Lombok 进行构造器注入

Service
@RequireArgsConstructor(onConstructor_ ={@Autowired}) 
public class TestServiceImpl implements TestService {private final TestDao testDao;}

或

@Service
@RequiredArgsConstructor(onConstructor_ = {@Autwired})
public class TestServiceImpl implements TestService {@lombok.NonNull private TestDao testDao;}

编译的内容

@Service
public class TestServiceImpl implements TestService {private TestDao testDao;@Autowiredpublic void TestServiceImpl(final TestDao testDao) {this.testDao = testDao;}
}
