Question

我尝试使用spring IOC初始化log4j logger并使用PropertyConfigurator.configure配置logger，但PropertyConfigurator.configure不起作用。使用默认配置创建记录器，不会创建记录文件。

我的问题是如何将配置（log4j.properties）传递给Logger类？

的pom.xml

<dependency>
        <groupId>org.springframework</groupId>
        <artifactId>spring-context</artifactId>
        <version>4.3.9.RELEASE</version>
    </dependency>
    <dependency>
        <groupId>log4j</groupId>
        <artifactId>log4j</artifactId>
        <version>1.2.17</version>
    </dependency>
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-web</artifactId>
          <version>1.5.5.RELEASE</version>
    </dependency>
   <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-test</artifactId>
        <scope>test</scope>
          <version>1.5.5.RELEASE</version>
    </dependency>

Confugration class

@Configuration 
public class CommonConfig {

@Autowired
private Environment env;

@PostConstruct
public void init() {
   PropertyConfigurator.configure("log4j.properties");
}

@Bean(name = "debugLogger")
public Logger debugLogger() {
    return Logger.getLogger("regDebug");
}

@Bean(name = "infoLogger")
public Logger infoLogger() {
    return Logger.getLogger("regOperational");
}

@Bean(name = "errorLogger")
public Logger errorLogger() {
  ic Logger infoLogger() {
    return Logger.getLogger("regError");
}}

Spring Boot通过spring-boot-starter-log4j依赖提供与Log4J的集成：

<dependency>
   <groupId>org.springframework.boot</groupId>
   <artifactId>spring-boot-starter-log4j</artifactId>
   <version>1.3.8.RELEASE</version>
</dependency>

但首先你需要排除默认的Spring Boot的日志记录机制：

<dependency>
   <groupId>org.springframework.boot</groupId>
   <artifactId>spring-boot-starter</artifactId>
   <exclusions>
      <exclusion>
         <groupId>org.springframework.boot</groupId>
         <artifactId>spring-boot-starter-logging</artifactId>
      </exclusion>
   </exclusions>
</dependency>

另外，请确保log4j.properties位于src/main/resources下方。在这种情况下，您无需明确指定文件的路径PropertyConfigurator，并且可以安全地删除init()方法。

请注意，Log4J 1.2.17已经过时了 - reached the end of life in 2015。您可能需要考虑使用Log4J2，或者使用Logback - Spring Boot使用的默认日志记录机制。

PropertyConfigurator.configure不适用于spring
