spring实现静态注入(类或者属性)操作示例

@Autowired
private TestService testService;
@Resource
private TestService testService;
@Value("${key}")
private String key;

@Autowired
private static TestService testService;
@Resource
private static TestService testService;
@Value("${key}")
private static String key;

@Component  
public class TestUtil {
   @Autowired    
   private static TestService testService;
   private static TestUtil testUtils;
      
   @PostConstruct      
   public void init() {          
      testUtils =this;          
      testUtils.testService =this.testService;      
   }  
}

@Component  
public class TestUtil {
       
   private static TestService testService;
   private static String key;
        @Value("{key}")
      public void setTestService(String key) {          
          TestUtil.key = key;      
       }  

        @Autowired
    public void setTestService(TestService testService) {          
          TestUtil.testService =this.testService;      
       }  
}
