I am trying to change the logging levels (from DEBUG to ERROR or WARN) at runtime in spring boot application. The code is given below.
我已关注以下帖子，但仍然发布更改日志记录级别的请求无效.请查看下面的请求，但应用程序没有响应，我也没有在日志中看到任何错误.
I have followed the below posts, but still posting the request to change the logging level did not work. Please look below for request and no response from application and I do not see any error in the logs either.

import org.springframework.web.bind.annotation.RestController;

SpringSecurityConfig
protected void configure(HttpSecurity http) throws Exception {
http.csrf().disable()
.authorizeRequests()
.antMatchers("/", "/home", "/about","/proxy/**","/app/**","/admin/**","/loggers/**","/loggers/de.springbootbuch/**",

.logout()

.exceptionHandling().accessDeniedHandler(accessDeniedHandler);
}
Application.properties，对这个文件有什么要处理的吗
logging.level.org.springframework.security=ERROR
logging.level.com.test=DEBUG
management.security.enabled=false
发送更改日志级别的请求:
curl -X "POST" "http://localhost:8080/loggers/de.springbootbuch" -H "Content-Type: application/json; charset=utf-8" -d $'{
"configuredLevel": "WARN"
}'
curl -X "POST" "http://localhost:8080/loggers/de.springbootbuch" -H "Content-Type: application/json; charset=utf-8" -d $'{
"configuredLevel": "ERROR"
}'
推荐答案
您可以使用 spring-boot 执行器的 loggers 端点来更改所需类的日志记录级别.在 spring-boot 1.5 中，您可以使用:
You can use spring-boot actuator's loggers endpoint to change logging level of desired class.
In spring-boot 1.5, you can use:
`curl -X "POST" "http://localhost:8080/loggers/<class or package name>" -H "Content-
Type: application/json; charset=utf-8" -d $'{
"configuredLevel": "ERROR"
}'`
从 spring-boot 执行器端点需要以 actuator 为前缀.
Starting with spring-boot actuator endpoints need to be prefixed with actuator.
