Question

我是Spring的开始，在spring事务方法中无法捕获catch块中的异常

@Path("/codes")
public class CodeFacadeREST extends AbstractFacade<Code> {

 @DELETE
 @Path("{id}")
 @Transactional
 public void remove(@PathParam("id") Integer id) throws RestException {
    try {
        log.info("Removing Entity  ::"+id );
        super.remove(super.find(id));
    } catch (Exception e) {
        // control never reach here
        log.error("Error ::: " + e.getMessage(), e);
        throw new RestException("Error ", e);
    }
  }
  //some other stuff
}

超级班是

 public abstract class AbstractFacade<T> {

 private Class<T> entityClass;

  public void remove(T entity)   {
        log.info("Deleting givne entity: " + entity);
        getEntityManager().remove(getEntityManager().merge(entity));
  }

 }

springconfiguration applicationContext.xml是

<context:annotation-config/>
<context:component-scan base-package="com.esq.rest.service,com.esq.rest.exception" />
<bean class="com.esq.rest.exception.RestExceptionMapper" scope="singleton" />
<!-- REST service beans -->    
<bean class="com.esq.rest.service.CodeFacadeREST" />

在运行时我可以在tomcat日志中看到以下异常

错误代码：20000 调用：DELETE FROM DICT.CODE WHERE（ID =？） bind =＆gt; [1参数界限] 查询：DeleteObjectQuery（com.vrs.pojo.Code [id = 1]）在org.springframework.orm.jpa.JpaTransactionManager.doCommit（JpaTransactionManager.java:522）在org.springframework.transaction.support.AbstractPlatformTransactionManager.processCommit（AbstractPlatformTransactionManager.java:755）在org.springframework.transaction.support.AbstractPlatformTransactionManager.commit（AbstractPlatformTransactionManager.java:724）在org.springframework.transaction.interceptor.TransactionAspectSupport.commitTransactionAfterReturning（TransactionAspectSupport.java:475） at org.springframework.transaction.interceptor.TransactionAspectSupport.invokeWithinTransaction（TransactionAspectSupport.java:270）在org.springframework.transaction.interceptor.TransactionInterceptor.invoke（TransactionInterceptor.java:94）在org.springframework.aop.framework.ReflectiveMethodInvocation.proceed（ReflectiveMethodInvocation.java:172）在org.springframework.aop.framework.CglibAopProxy $ DynamicAdvisedInterceptor.intercept（CglibAopProxy.java:631）在com.esq.rest.service.CodeFacadeREST $$ EnhancerByCGLIB $$ 9bec2548.remove（）

然而同样没有抓住方法尝试catch，我希望这是由于代理。有没有办法解决这个问题。

编辑：

我想通过异常映射器捕获并响应它。

@Provider
public class RestExceptionMapper implements ExceptionMapper<RestException> {
     // response user readable form
}

Spring Transactional方法异常永远不会捕获
