ajax返回错误处理
ajax返回异常处理
ajax发出的请求要考虑接收方式和返回方式一致
@ResponseBody会自己处理乱码问题（前提xml要配置好）
方式一：
<bean class="org.springframework.web.servlet.view.ContentNegotiatingViewResolver">
<property name="order" value="3" />
<property name="defaultViews">
<list>
<bean class="org.springframework.web.servlet.view.json.MappingJackson2JsonView"/>
</list>
</property>
</bean>
方式二：
<!-- 采用SpringMVC自带的JSON转换工具，支持@ResponseBody注解 -->
<bean
class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter">
<property name="messageConverters">
<list>
<bean
class="org.springframework.http.converter.json.MappingJacksonHttpMessageConverter" />
</list>
</property>
</bean>
<!-- 避免IE执行AJAX时,返回JSON出现下载文件 -->
<bean id="mappingJacksonHttpMessageConverter"
class="org.springframework.http.converter.json.MappingJacksonHttpMessageConverter">
<property name="supportedMediaTypes">
<list>
<value>text/html;charset=UTF-8</value>
</list>
</property>
</bean>
正常时直接用返回数据
错误时用responseText获取返回数据
//添加保存
function edit(){
if(!check()){
return false;
}
$.ajax({
url:"${path}/myaccount/eidtUser",
type:"post",
cache:false,
async:true,
dataType:"json",
data:$("#operateUserEditForm").serialize(),
success:function(ret){
if(ret==''||ret==null){
alert("操作成功！")
window.location.href="${path}/myaccount/getAccount";
}else{
//alert(2);
//alert(ret);
}
},
error:function(retMsg){
alert(eval("("+retMsg.responseText+")").msg);
}
});
}
@RequestMapping(value = "/eidtUser")
@ResponseBody
public String eidtUser(Model model,TbCusUserBeanVo tbCusUserBeanVo, @RequestParam(value="rolesKey") String rolesKey,@RequestParam(value="pz") String[] pz,HttpServletRequest request, HttpSession session) throws Exception {
CusUserBean getCusUser= CASUtil.getCusUser(request, session);
if(tbCusUserBeanVo==null){
return null;
}
tbCusUserBeanVo.setCustomerKey(BigDecimal.valueOf(Long.valueOf(getCusUser.getCustomerKey())));
try{
accountService.editOperateUser(tbCusUserBeanVo, rolesKey, pz);
}catch(Exception e){
e.printStackTrace();
return "{msg:'"+e.getMessage()+"'}";
//"{msg:"+e.getMessage()+"}"throw new Exception(e.getMessage()); //new String( e.getMessage().getBytes(),"utf-8");URLEncoder.encode(e.getMessage(),"utf-8")
}
return "";
}
