修改 Spring Security 的日志级别

1、概览 {#1概览}

使用 Spring Security 时,可能需要把日志级别设置得更高一些。例如,可能需要检查用户的角色或端点的安全配置。或者,可能还需要更多关于身份认证或授权的信息,例如查看为什么用户无法访问某个端点。

本文将带你了解如何修改 Spring Security 日志级别。

2、配置 Spring Security 日志 {#2配置-spring-security-日志}

与其他 Spring 或 Java 应用一样,可以使用日志库,并为 Spring Security 模块定义日志级别。

通常,可以进行如下配置:

<logger name="org.springframework.security" level="DEBUG" />

如果运行的是 Spring Boot 应用,则可以在 application.properties 文件中对此进行配置:

logging.level.org.springframework.security=DEBUG

同样,也可以使用 yaml:

logging:
  level:
    org:
      springframework:
        security: DEBUG

这样,就可以查看有关身份认证或 Filter Chain 的日志。此外,还可以使用 trace 级别进行更深入的 debug。

Spring Security 还能记录有关请求和应用的 Filter 的特定信息:

@EnableWebSecurity
public class SecurityConfig {

    @Value("${spring.websecurity.debug:false}")
    boolean webSecurityDebug;

    @Bean
    public WebSecurityCustomizer webSecurityCustomizer() {
        return (web) -> web.debug(webSecurityDebug);
    }
    // ...
}

3、日志示例 {#3日志示例}

定义一个简单的 Controller 来测试应用:

@Controller
public class LoggingController {

    @GetMapping("/logging")
    public ResponseEntity<String> logging() {
        return new ResponseEntity<>("logging/baeldung", HttpStatus.OK);
    }

}

访问 /logging 端点,就可以看到日志:
