# 78.2.1 使用YAML或JSON配置Log4j2

除了它的默认XML配置格式，Log4j 2也支持YAML和JSON配置文件。想使用其他配置文件格式配置Log4j 2，你需要添加合适的依赖到classpath，并以匹配所选格式的方式命名配置文件：

| 格式   | 依赖                                                                                                       | 文件名                        |
| ---- | -------------------------------------------------------------------------------------------------------- | -------------------------- |
| YAML | `com.fasterxml.jackson.core:jackson-databind` `com.fasterxml.jackson.dataformat:jackson-dataformat-yaml` | `log4j2.yaml` `log4j2.yml` |
| JSON | `com.fasterxml.jackson.core:jackson-databind`                                                            | `log4j2.json` `log4j2.jsn` |
