## SpringBoot运行中动态修改logback日志级别 ##

思路：写一个api接口，通过api接口调用的方式动态修改logback的log日志打印级别

这里提供2个接口，分别是修改logback全局日志级别 ，和单独修改某个package包的日志级别

package cn.demo.rest;
    
    import ch.qos.logback.classic.Level;
    import ch.qos.logback.classic.LoggerContext;
    import lombok.extern.slf4j.Slf4j;
    import org.slf4j.LoggerFactory;
    import org.springframework.beans.factory.annotation.Autowired;
    import org.springframework.http.MediaType;
    import org.springframework.validation.annotation.Validated;
    import org.springframework.web.bind.annotation.*;
    
    
    @Slf4j
    @RestController
    public class CloudApi {
        
    
    //--------------------------------------------------------------------
        /*
    http://localhost:8627/iotcenter/alterLogLevel/info
         */
        @GetMapping("/alterSysLogLevel/{level}")
        public String alterSysLogLevel(@PathVariable String level){
        
            LoggerContext context = (LoggerContext) LoggerFactory.getILoggerFactory();
            context.getLogger("ROOT").setLevel(Level.valueOf(level));
            return "ok";
        }
    
    
        /*
    http://localhost:8627/iotcenter/alterPkgLogLevel?level=info&pkgName=com.xx.xxx
         */
    
        @GetMapping("/alterPkgLogLevel")
        public String alterPkgLogLevel(@RequestParam String level, @RequestParam String pkgName){
        
            LoggerContext context = (LoggerContext) LoggerFactory.getILoggerFactory();
            context.getLogger(pkgName).setLevel(Level.valueOf(level));
            return "ok";
        }
    
    
    
    }
