如何注冊 ContainerRequestFilter 並將變量傳遞給它？

Question

有沒有辦法將 ContainerRequestFilter 注冊到 ResourceConfig 並將變量傳遞給它的構造函數？

以下是過濾器代碼

public class TestRequestFilter implements ContainerRequestFilter{
   String operationType;

   public TestRequestFilter (){}

   public TestRequestFilter (String opType){
      this.operationType = opType;
   }
   
   @Override
   public void filter(ContainerRequestContext requestContext) {
    // TODO Auto-generated method stub
    
   }
}

為了注冊這個過濾器，我使用了 ResourceConfig 如下

public class MyApplication extends ResourceConfig {

/**
 * Register JAX-RS application components.
 */
public MyApplication () {
    register(TestRequestFilter.class);
    register(JacksonFeature.class);
    register(CustomerResource.class);
    register(Initializer.class);
    register(JerseyResource.class);
}
}

有什么方法可以用 opType 構造函數注冊這個過濾器嗎？

Answer 1

使用單個構造函數創建 class，創建 object 並注冊創建的 object。

public class TestRequestFilter implements ContainerRequestFilter{
   private String operationType;

   public TestRequestFilter (String opType){
      this.operationType = opType;
   }
   
   @Override
   public void filter(ContainerRequestContext requestContext) {
       //your code
   }
}

登記：

ResourceConfig.register(new TestRequestFilter("osType"));
