SpringBoot动态修改日志级别

SpringBoot1.5新特性

目录

1. 安装依赖
2. 测试显示日志级别
3. 测试修改日志级别

1.在pom中添加依赖

<parent>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-parent</artifactId>
    <version>1.5.1.RELEASE</version>
    <relativePath/> <!-- lookup parent from repository -->
</parent>
<dependencies>
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-actuator</artifactId>
    </dependency>
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-web</artifactId>
    </dependency>
</dependencies>

2.开始测试

http://localhost:8080/loggers

服务:

s.b.a.e.m.MvcEndpointSecurityInterceptor : Full authentication is required to access actuator endpoints. Consider adding Spring Security or set 'management.security.enabled' to false.

需要手动设置management.security.enabled=false

• 继续测试

http://localhost:8080/loggers

服务返回:

{
levels: [
"OFF",
"ERROR",
"WARN",
"INFO",
"DEBUG",
"TRACE"
],
loggers: {
ROOT: {
configuredLevel: "INFO",
effectiveLevel: "INFO"
},
elephant: {
configuredLevel: "DEBUG",
effectiveLevel: "DEBUG"
},
...

3.修改日志级别

POST请求
http://localhost:8080/loggers/{elephant}

{}中根据/loggers方法返回的目录级别添加

eg:

我要修改elephant.zybank.rest目录下级别

就使用下面请求方法

http://localhost:8080/loggers/elephant.zybank.rest

请求体中使用json

{
    "configuredLevel": "DEBUG"
}

登录服务器

curl -H "Content-Type: application/json" -X POST --data 
'
{
    "configuredLevel": "DEBUG"
}
' 
http://localhost:8080/loggers/elephant.zybank.rest
