介绍
根据 springboot 自定义404、500错误页 的方式二实现
实现配置类
package top.malaoshi.stdsecurity.config;
import org.springframework.boot.web.server.ErrorPage;
import org.springframework.boot.web.server.ErrorPageRegistrar;
import org.springframework.boot.web.server.ErrorPageRegistry;
import org.springframework.context.annotation.Configuration;
import org.springframework.http.HttpStatus;
@Configuration
public class ErrorPageConfig implements ErrorPageRegistrar {
@Override
public void registerErrorPages(ErrorPageRegistry registry) {
/*报404错误时，转发到/error/404 */
ErrorPage e404 = new ErrorPage(HttpStatus.NOT_FOUND, "/error/404");
/*报500错误时，转发到/error/500 */
ErrorPage e500 = new ErrorPage(HttpStatus.INTERNAL_SERVER_ERROR, "/error/500");
registry.addErrorPages(e404, e500);
}
}
- 报404错误时，转发 到
/error/404 - 报500错误时，转发 到
/error/500
创建Controller
package top.malaoshi.stdsecurity.controller;
import org.springframework.http.HttpStatus;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
import top.malaoshi.stdsecurity.json.Result;
@RestController
@RequestMapping(value = "/error")
public class ErrorController {
@RequestMapping(value = "/404")
public Result error404() {
return new Result(HttpStatus.NOT_FOUND.value(),HttpStatus.NOT_FOUND.getReasonPhrase());
}
@RequestMapping(value = "/500")
public Result error500() {
return new Result(HttpStatus.INTERNAL_SERVER_ERROR.value(),HttpStatus.INTERNAL_SERVER_ERROR.getReasonPhrase());
}
}
创建bean
package top.malaoshi.stdsecurity.json;
public class Result {
private int code;
private String msg;
public Result(){
}
public Result(int code, String msg) {
this.code = code;
this.msg = msg;
}
public int getCode() {
return code;
}
public void setCode(int code) {
this.code = code;
}
public String getMsg() {
return msg;
}
public void setMsg(String msg) {
this.msg = msg;
}
}
