1. 添加config 配置类
-
package org.fh.config;
-
-
-
import javax.servlet.http.HttpServletRequest;
-
import javax.servlet.http.HttpServletResponse;
-
-
import org.springframework.context.annotation.Configuration;
-
import org.springframework.web.servlet.HandlerExceptionResolver;
-
import org.springframework.web.servlet.ModelAndView;
-
import org.springframework.web.servlet.view.json.MappingJackson2JsonView;
-
-
/**
-
* 说明:错误异常拦截处理
-
* 作者:FH Admin
-
* from fhadmin.cn
-
*/
-
@Configuration
-
public class ExceptionConfiguration implements HandlerExceptionResolver {
-
-
@Override
-
public ModelAndView resolveException(HttpServletRequest request, HttpServletResponse response, Object handler,
-
Exception ex) {
-
ModelAndView mv = new ModelAndView(new MappingJackson2JsonView()); //返回json
-
-
String exInfo = ex.toString().replaceAll("\n", "
");
-
-
boolean status = exInfo.contains("Subject does not have permission");
-
-
if(status){
-
exInfo = "[没有此页面的访问权限]" + exInfo;
-
}else {
-
System.out.println("==============异常开始=============");
-
ex.printStackTrace();
-
System.out.println("==============异常结束=============");
-
}
-
mv.addObject("exception", exInfo);
-
mv.addObject("result", "exception");
-
-
return mv;
-
}
-
-
}
2. 在逻辑类的方法上抛出异常 throws Exception,比如
-
/**删除
-
* @param out
-
* @throws Exception
-
*/
-
@RequestMapping(value="/delete")
-
@RequiresPermissions("autograph:del")
-
@ResponseBody
-
public Object delete() throws Exception{
-
Map<String,String> map = new HashMap<String,String>();
-
String errInfo = "success";
-
//xxxx
-
map.put("result", errInfo); //返回结果
-
return map;
-
}
3. 前端页面接收异常结果
-
//发送 post 请求提交保存
-
$.ajax({
-
xhrFields: {
-
withCredentials: true
-
},
-
type: "POST",
-
url: httpurl+'xxxx/delete',
-
data: {tm:new Date().getTime()},
-
dataType:"json",
-
success: function(data){
-
if("success" == data.result){
-
-
}else if ("exception" == data.result){
-
alert("模块异常"+data.exception);//显示异常
-
-
}
-
}
-
})
