spring boot 搭建:

java -jar -Dserver.port=10000 -Dlogging.path=/var/logs xxx.jar &   -- 默认在/var/logs/生成spring.log文件     java -jar -Dserver.port=10001 -Dlogging.file=/var/logs/yyy.log yyy.jar &     -- 指定虚拟机内存、日志文件、配置文件，启动SpringBoot项目   java -Xms256m -Xmx512m -jar -Dlogging.file=/var/logs/ebag-school.log LK-school-1.0.jar --spring.config.location=school-prod.yml &

基本配置:

server:    port: 8090  //配置端口

全局异常处理:

拦截捕捉自定义异常 MyException.class

我的异常类：

/**

* @Auther: cookie

* @Date: 2018/7/26 15:22

* @Description:

*/

public class MyException extends RuntimeException{

private String code;  //异常状态码

private String message;  //异常信息

private String method;   //发生的方法，位置等

private String descinfo;   //描述

public MyException(String code, String message, String method, String descinfo) {

this.code=code;

this.message=message;

this.method=method;

this.descinfo=descinfo;

}

public String getCode() {

return code;

}

public void setCode(String code) {

this.code = code;

}

public String getMessage() {

return message;

}

public void setMessage(String message) {

this.message = message;

}

public String getMethod() {

return method;

}

public void setMethod(String method) {

this.method = method;

}

public String getDescinfo() {

return descinfo;

}

public void setDescinfo(String descinfo) {

this.descinfo = descinfo;

}

}

/**

* @Description: 全局捕获异常和自定义全局捕获异常

*/

@ControllerAdvice  //不指定包默认加了@Controller和@RestController都能控制

//@ControllerAdvice(basePackages ="com.example.demo.controller")

public class MyControllerAdvice {

/**

* @param myex

* @return

*/

@ResponseBody

@ExceptionHandler(value = MyException.class)

public Map<String,Object> myExceptionHandler(MyException myex){

Map<String,Object> map  = new HashMap<String,Object>();

map.put("code",myex.getCode());

map.put("message",myex.getMessage());

map.put("method",myex.getMethod());

map.put("descinfo",myex.getDescinfo());

//发生异常进行日志记录，写入数据库或者其他处理，此处省略

return map;
