java - Maven Spring 项目给我 org.slf4j.spi.LocationAwareLogger 错误

Question

Maven Spring 项目给了我

org.slf4j.spi.LocationAwareLogger.log(Lorg/slf4j/Marker;Ljava/lang/String;ILjava/lang/String;Ljava/lang/Throwable error

这是我第一次使用 Eclipse 和 Maven。我总是在 Eclipse 中完成我的 Spring 项目，但我只是开始将 Maven 用于 JAR。如果我在服务器上运行我的新项目，我会收到此错误:

SEVERE: Exception sending context initialized event to listener instance of class org.springframework.web.context.ContextLoaderListener

这是我的 pom.xml 文件，一定是少了什么

请帮帮我

Answer 1

您可以使用 mvn-plugin maven-enforcer-plugin 来识别您的commons-logging 的问题。

将此代码段添加到您的master 或parent pom.xml

<plugins>
  <plugin>
    <artifactId>maven-enforcer-plugin</artifactId>
    <version>1.1.1</version>
    <executions>
      <execution>
        <id>enforce-banned-dependencies</id>
        <goals>
          <goal>enforce</goal>
        </goals>
        <configuration>
          <rules>
            <bannedDependencies>
              <searchTransitive>true</searchTransitive>
              <excludes>
                <exclude>commons-logging</exclude>
                <exclude>org.slf4j:1.5*</exclude>
                <exclude>org.slf4j:1.6*</exclude>
                <exclude>org.springframework:2.*</exclude>
                <exclude>org.springframework:3.0.*</exclude>
              </excludes>
            </bannedDependencies>
          </rules>
          <fail>true</fail>
        </configuration>
      </execution>
    </executions>
  </plugin>
  ......
</plugins>

您的项目中用于在 log4j 中记录 slf4j 的正确 mvn-configuration 可能是:

<dependencies>
    <dependency>
        <groupId>org.slf4j</groupId>
        <artifactId>slf4j-api</artifactId>
        <version>1.7.1</version>
    </dependency>
    <!-- slf4j-bridge for commons-logging -->
    <dependency>
        <groupId>org.slf4j</groupId>
        <artifactId>jcl-over-slf4j</artifactId>
        <version>1.7.1</version>
    </dependency>
    <dependency>  
        <groupId>org.slf4j</groupId>  
        <artifactId>slf4j-log4j12</artifactId>  
        <version>1.7.1</version>  
    </dependency>
    ...
</dependencies>

这会产生 e。 G。那个错误

...
[INFO] --- maven-enforcer-plugin:1.1.1:enforce (enforce-banned-dependencies) @ sd4h ---
[WARNING] Rule 0: org.apache.maven.plugins.enforcer.BannedDependencies failed with message:
Found Banned Dependency: commons-logging:commons-logging:jar:1.1.1
Use 'mvn dependency:tree' to locate the source of the banned dependencies.
...

可以解决，当它在你的mvn配置中被排除 e。 g.

<dependencies>
    <dependency>
        <groupId>org.springframework</groupId>
        <artifactId>spring-context</artifactId>
        <version>3.1.2.RELEASE</version>
        <exclusions>
            <exclusion>
                <artifactId>commons-logging</artifactId>
                <groupId>commons-logging</groupId>
            </exclusion>
        </exclusions>
    </dependency>
    ...
</dependencies>
