1、概览
2、在《springboot - 返回JSON error 从自定义的 ErrorController》基础上，做如下调整：
1）、新增Attribute类和Error类
package com.ebc.controller;import javax.xml.bind.annotation.XmlRootElement;@XmlRootElement
public class Attribute {
private String key;
private String value; public String getKey() {
return key;
} public void setKey(String key) {
this.key = key;
} public String getValue() {
return value;
} public void setValue(String value) {
this.value = value;
}
}
package com.ebc.controller;import javax.xml.bind.annotation.XmlAccessType;
import javax.xml.bind.annotation.XmlAccessorType;
import javax.xml.bind.annotation.XmlElement;
import javax.xml.bind.annotation.XmlRootElement;
import java.util.List;@XmlRootElement
@XmlAccessorType(XmlAccessType.FIELD)
public class Error {
@XmlElement(name="attribute")
private List<Attribute> attributeList; public List<Attribute> getAttributeList() {
return attributeList;
} public void setAttributeList(List<Attribute> attributeList) {
this.attributeList = attributeList;
}
}
2）、修改MyCustomErrorController类
import org.springframework.boot.autoconfigure.web.servlet.error.AbstractErrorController;
import org.springframework.boot.web.servlet.error.ErrorAttributes;
import org.springframework.http.MediaType;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.ResponseBody;import javax.servlet.http.HttpServletRequest;
import java.util.ArrayList;
import java.util.List;
import java.util.Map;/**
* @author www.gomepay.com
* @date 2019/11/18
*/
@Controller
public class MyCustomErrorController extends AbstractErrorController {
public MyCustomErrorController(ErrorAttributes errorAttributes) {
super(errorAttributes);
}
@RequestMapping(value = "/error", produces = MediaType.APPLICATION_XML_VALUE)
@ResponseBody
public Error handleError(HttpServletRequest request) {
Map<String, Object> errorAttributes = super.getErrorAttributes(request, true); List<Attribute> attributes = new ArrayList<>();
errorAttributes.forEach((key, value) -> {
Attribute attribute = new Attribute();
attribute.setKey(key);
attribute.setValue(value == null ? "" : value.toString());
attributes.add(attribute);
});
Error error = new Error();
error.setAttributeList(attributes);
return error;
}
@Override
public String getErrorPath() {
return "/error";
}
}
3、执行
1）、http://localhost:8080/
<?xml version="1.0" encoding="utf-8"?><error>
<attribute>
<key>timestamp</key>
<value>Wed Nov 20 17:43:59 GMT+08:00 2019</value>
</attribute>
<attribute>
<key>status</key>
<value>500</value>
</attribute>
<attribute>
<key>error</key>
<value>Internal Server Error</value>
</attribute>
<attribute>
<key>message</key>
<value>test exception</value>
</attribute>
<attribute>
<key>trace</key>
<value>java.lang.RuntimeException: test exception at com.ebc.controller.MyController.handler(MyController.java:15)。。。</value>
</attribute>
<attribute>
<key>path</key>
<value>/</value>
</attribute>
</error>
2）、http://localhost:8080/other
<?xml version="1.0" encoding="utf-8"?><error>
<attribute>
<key>timestamp</key>
<value>Wed Nov 20 17:49:51 GMT+08:00 2019</value>
</attribute>
<attribute>
<key>status</key>
<value>404</value>
</attribute>
<attribute>
<key>error</key>
<value>Not Found</value>
</attribute>
<attribute>
<key>message</key>
<value>No message available</value>
</attribute>
<attribute>
<key>path</key>
<value>/other</value>
</attribute>
</error>
