如何獲得HTTP狀態代碼爲REST服務騾子

Question

我有以下騾子流量： -

<jms:activemq-connector name="Active_MQ" brokerURL="tcp://localhost:61616" validateConnections="true" doc:name="Active MQ"/> 

    <mule-ss:security-manager> 
     <mule-ss:delegate-security-provider name="memory-provider" delegate-ref="authenticationManager" /> 
    </mule-ss:security-manager> 
    <spring:beans> 
     <ss:authentication-manager alias="authenticationManager"> 
      <ss:authentication-provider> 
       <ss:user-service id="userService"> 
        <ss:user name="username" password="password" authorities="ROLE_ADMIN" /> 
       </ss:user-service> 
      </ss:authentication-provider> 
     </ss:authentication-manager> 
    </spring:beans> 

<flow name="testFlow1" doc:name="testFlow1"> 
<http:inbound-endpoint exchange-pattern="request-response" host="localhost" port="8083" doc:name="HTTP"> 
    <mule-ss:http-security-filter realm="realm" /> 
</http:inbound-endpoint> 

<jersey:resources doc:name="REST"> 
    <component class="MyRest" /> 
    </jersey:resources> 

<logger message="Done !!!!!" level="INFO" doc:name="Logger"/> 

    <!-- http://username:password@localhost:8083/myrest or http://localhost:8083/myrest and in this case we need to provide username and password from browser--> 

<catch-exception-strategy> 
    <choice > 
    <when expression="#[exception.getCauseException().getClass().getName()=='org.springframework.security.authentication.BadCredentialsException']"> 
    <logger level="INFO" message="Authentication failed exception: #[exception.getCauseException().getClass().getName()]"/> 
    <set-property propertyName="http.status" value="401"/> 
    <http:response-builder status="401" doc:name="Status code = 401" doc:description="Authentication failed"/> 
     </when> 
     <when expression="#[exception.getCauseException().getClass().getName()=='org.springframework.security.access.AccessDeniedException']"> 
     <logger level="INFO" message="Access denied exception: #[exception.getCauseException().getClass().getName()]"/> 
     <set-property propertyName="http.status" value="405"/> 
    <http:response-builder status="405" doc:name="Status code = 405" doc:description="Authorization exception - Access denied"/> 
    </when> 
     <otherwise> 
     <logger message="An exception has been caught: #[exception.getCauseException().getClass().getName()]" level="ERROR" doc:name="Exception Thrown"/> 
    <set-payload value="Error detected while processing" doc:name="Prepare response for client"/> 
    <set-property propertyName="http.status" value="500"/> 
    <http:response-builder status="500" doc:name="Status code = 500" doc:description="Exception - Sending a 500 Http Status code as Response"/> 
    </otherwise> 
     </choice> 
    </catch-exception-strategy> 

    </flow> 

我採取了以下作爲參考： - https://github.com/daveEason/mule-example-spring-security/blob/master/src/main/app/mule-config.xml

現在的問題，只要我打的網址： - http://localhost:8083/myrest ...我得到以下異常： -

我不知道它爲什麼產生這樣的例外..

但是，如果我從代碼中刪除異常塊，打http://localhost:8083/myrest它工作正常，並要求用戶名和密碼預期，併產生預期的結果..

但我不知道它爲什麼產生當我使用異常塊代碼例外.. 其實我使用異常塊的目的是獲取和在不同的情況

Answer 1

有在玩兩樣東西在這裏：

1. 異常，由新澤西州的資源

   這種異常必須要處理拋出由一個或多個自定義JAX-RS異常處理程序，通過一個或多個jersey:exception-mapper元素註冊到jersey:resources。

2. 例外通過mule-ss:http-security-filter

   這些異常是由騾子JAX-RS的範圍之外拋甩，所以他們必須處理由catch-exception-strategy元素，正如你在你的問題一樣。

有了這種錯誤處理的組合應該爲你提供你所需要的。

Answer 2

控制不同的HTTP狀態

來檢索HTTP代碼，您可以使用過濾器並在流程中引發異常。下面一個例子：

<message-filter throwOnUnaccepted="true"> 
    <message-property-filter pattern="message.inboundProperties['http.status'] >= 400" /> 
</message-filter>
