使用wsgen和@Interceptors原因 - >不支持major.minor版本51.0

我有一個Java EE項目打包在耳邊。耳朵包含一個Jar，我打包了我的@stateless EJB和其他未管理的類（我的模型，utils等）。對於其中一些EJB，我使用Jax-W將它們的功能作爲Web服務公開。使用wsgen和@Interceptors原因 - >不支持major.minor版本51.0

我嘗試使用AOP創建日誌記錄機制，因此我將@Interceptors註釋放入Jax-Ws驅動的EJB中。問題是，當我嘗試使用maven編譯/構建/包時，我收到以下異常。這似乎是問題是特定於wsgen的原因，當我把@Interceptors註釋在NON Jax-ws註釋的EJBs編譯和運行沒有任何問題。我使用JAva build 1.6.0_41-b02。

我也試着找到javax.interceptor-api的老版本（可能在Java 1.6中編譯，因爲major.minor版本51.0意味着它已經在JSE 7中編譯，如果我正確的話），但似乎是1.2是較老的一個。

您嘗試web-beans.xml代替annotation？如果沒有請檢查this is link。可能是Maven插件不認識這個註釋。

類級別的聲明應該是這樣的代碼：

<myapp:MyWebServiceBean> 
    <myfwk:LoggingAopService/> 
</myapp:MyWebServiceBean>

而且這個攔截器需要啓用：

<Interceptors> 
    <myfwk:LoggingAopService/> 
</Interceptors>

我沒有測試這些代碼。

您發送的web-beans.xml聲明是特定於jboss的？我使用Web邏輯並發現可以通過在META-INF/beans.xml中添加以下xml來啓用攔截器。

<interceptors> 
    <class>org.samples.LoggingInterceptor</class> 
</interceptors>

我會盡量XML聲明，而是因爲我很着急，我利用由JAX-WS框架本身提供的處理程序的功能（使用@HandlerChain批註）爲「攔截」的Web服務請求和響應。

我也嘗試使用@InterceptorBinding方法來建立一個新的註釋：

@Inherited 
    @InterceptorBinding 
    @Retention(RUNTIME) 
    @Target({ METHOD, TYPE }) 
    public @interface Logging { 
    } 



@Interceptor 
    @Logging 
    public class LoggingInterceptor { 
     @AroundInvoke 
     public Object intercept(InvocationContext context) throws Exception {...} 



@Logging 
    @WebService(serviceName = "MyWebService", portName = "MyWebService", 
    targetNamespace = "...") 
    @Stateless(name = "MyWebServiceBean", mappedName = "ejb/seb/MyWebServiceBean") 
    public class MyWebServiceBean implements MyWebService 
    {....}

但這並不編譯過，我收到了同樣的錯誤：

[ERROR] Failed to execute goal org.jvnet.jax-ws-commons:jaxws-maven-plugin:2.2:w 
sgen (EDocWebService) on project eDoc-ws-ejb: Failed to execute wsgen: javax/int 
erceptor/InterceptorBinding : Unsupported major.minor version 51.0 -> [Help 1]

也許這是一個情況下，應使用ejb-jar.xml

<?xml version="1.0" encoding="UTF-8"?> 
    <ejb-jar xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
     version="3.0" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/ejb-jar_3_0.xsd"> 
     <interceptors> 
     <interceptor> 
      <interceptor-class>com.mypackage.LoggingInterceptor </interceptor-class> 
     </interceptor> 
     </interceptors> 

     <assembly-descriptor> 
     <interceptor-binding> 
      <ejb-name>MyWebServiceBean</ejb-name> 
      <interceptor-class>com.package.Interceptor</interceptor-class> 
     </interceptor-binding> 
     </assembly-descriptor> 
</ejb-jar>
