springcloud之logback-spring打印异常信息

最近打算把项目部署到虚拟机上进行测试，发现没有报错信息，后来研究了下，项目里面几乎都使用了try...catch，这就导致输出的日志里面没有异常信息，下面直接上代码。

logback-spring.xml配置

<?xml version="1.0" encoding="UTF-8"?>
    <configuration debug="false">
        
        <property name="LOG_HOME" value="/logs"/>
    
        
        <appender name="console" class="ch.qos.logback.core.ConsoleAppender">
            
            <encoder class="ch.qos.logback.classic.encoder.PatternLayoutEncoder">
                
                <pattern>%d{yyyy-MM-dd HH:mm:ss.SSS} [%thread] %-5level %logger{50} - %msg%n</pattern>
                
                <charset>UTF-8</charset>
            </encoder>
        </appender>
    
        
        <appender name="timeFileOutput" class="ch.qos.logback.core.rolling.RollingFileAppender">
            
            <File>${LOG_HOME}/lightSystemMan/out.log</File>
            
            <rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
                
                <FileNamePattern>${LOG_HOME}/lightSystemMan/info.%d{yyyy-MM-dd}.%i.log.gz</FileNamePattern>
                
                <MaxHistory>30</MaxHistory>
                
                <timeBasedFileNamingAndTriggeringPolicy class="ch.qos.logback.core.rolling.SizeAndTimeBasedFNATP">
                    <maxFileSize>100MB</maxFileSize>
                </timeBasedFileNamingAndTriggeringPolicy>
            </rollingPolicy>
    
            
            <encoder class="ch.qos.logback.classic.encoder.PatternLayoutEncoder">
                
                <pattern>%d{yyyy-MM-dd HH:mm:ss.SSS} [%thread] %-5level %logger{50} - %msg%n</pattern>
                
                <charset>UTF-8</charset>
            </encoder>
    
        </appender>
    
        
        <root level="INFO">
            
            <appender-ref ref="console"/>
            <appender-ref ref="timeFileOutput"/>
        </root>
    </configuration>

application.yml配置

logging:
      config: classpath:logback-spring.xml

java代码设置

import org.apache.commons.lang.exception.ExceptionUtils;
    import org.slf4j.Logger;
    import org.slf4j.LoggerFactory;
    //引入的包
    
    private static final Logger logger = LoggerFactory.getLogger(AssetsManagementController.class);    
    //在每一个try...catch的方法上加上@ExceptionHandler(Exception.class)注解
        @ExceptionHandler(Exception.class)
        @RequestMapping("/queryTerminal")
        public JsonResult queryTerminal(@RequestParam Map<String, Object> params){
            IPage page=null;
            try {
                page=assetsManagementService.queryTerminal(params);
            }catch (Exception e){
    //            e.printStackTrace();
    //将异常打印换成错打印
                logger.error(ExceptionUtils.getFullStackTrace(e));
                Map map=new HashMap();
                map.put("msg","程序异常");
                map.put("flag",false);
                return new JsonResult(map);
            }
            return new JsonResult(page);
        }

@ExceptionHandler：统一处理某一类异常，从而能够减少代码重复率和复杂度
