我编写了以下代码以实现Spring Exception处理。当我运行代码时，需要在下面的行中抛出一个错误，并执行相应的异常处理程序。但是，它没有执行。我可以知道我的代码有什么问题。提前致谢
throw new SpringException("Error", retStatus);
代码：
@Controller
public class RestController {
@ExceptionHandler(SpringException.class)
public String handleCustomException(SpringException ex) {
String jsonInString = "{}";
JSONObject json = new JSONObject();
Map<String,String> errorMap = new HashMap<String,String>();
errorMap.put("errorMessage",ex.getMessage());
System.out.println("Inside exception handler");
json.putAll(errorMap);
jsonInString = json.toJSONString();
logger.info(jsonInString);
return jsonInString;
}
@RequestMapping(value = "/v1/dist_list/{emailId}/members", method = RequestMethod.GET)
public @ResponseBody String getDistributionListMember(@PathVariable String emailId) throws Exception, SpringException {
String retStatus = null;
retStatus = dataServices.getDistributionListMember(emailId, callerId);
if (!retStatus.isEmpty()) {
if (retStatus.contains("callerid is not valid")) {
throw new SpringException("Error", retStatus);
}
}
}
SpringException类
package com.uniteid.model;
import org.springframework.http.HttpStatus;
public class SpringException extends RuntimeException {
private static final long serialVersionUID = 1L;
private String errCode;
private String errMsg;
public String getErrCode() {
return errCode;
}
public void setErrCode(String errCode) {
this.errCode = errCode;
}
public String getErrMsg() {
return errMsg;
}
public void setErrMsg(String errMsg) {
this.errMsg = errMsg;
}
public SpringException(String errCode, String errMsg) {
this.errCode = errCode;
this.errMsg = errMsg;
}
}
下面是我的Spring-config.xml文件

我在控制台的代码行
中收到以下错误 throw new SpringException("Error", retStatus);
