Maven Spring Project givinig me org.slf4j.spi.LocationAwareL

Question

Maven Spring Project givinig me

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，但我刚刚开始将Maven用于JAR。如果我在服务器上运行我的新项目，我会收到以下错误：

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

这是我的pom.xml文件，一定缺少什么

您可以使用mvn插件maven enforcer插件来识别您的commons日志记录的问题。

将此代码段添加到主或父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>

在您的项目中，在log4j内记录slf4j的正确mvn配置可以是：

<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>

这可能会产生例如错误

...
[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.
...

当它在mvn配置中被排除时，它可以被解决，例如

<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>

我遇到了同样的问题，我解决了它更新了jcl-over-slf4jjar文件。我使用的是1.7.5版本，它已成功部署。

这是我的pom.xml的依赖项。希望这对你有所帮助。

Answer 3

运行

mvn dependency:tree或mvn dependency:list来获得所有依赖项的列表，包括可传递依赖项。

Answer 4

这个问题困扰我已经有一段时间了，它似乎吸引了很多人。（另请参阅此处）STS的新安装，下载最新的MVC模板，构建正常，由于这个SLF4J问题而不会运行。

这个问题似乎是slf4j库和maven使用的依赖项之间的不兼容。

简单的解决方案（这里）是编辑pom并删除commons日志的排除，然后删除slf4j的依赖项。当slf4j不可用时，Spring会返回到commons日志记录。我放弃了一个更难的解决方案，那就是追踪哪些版本可以与当前的STS（3.1）一起使用，并确保模板与正确的版本一起使用。

我希望这篇文章能帮助其他尝试过模板的人，但不能让它像应该的那样开箱即用。

Answer 5

一些公共日志记录库和其中一个slf4j库之间存在一些版本冲突。（这不是一个maven问题，如果你也手动维护libs，就会出现这个问题。）

使用eclipse打开maven pom。有一个名为"hirarchy"的选项卡，它将显示使用的和需要的版本。尽量使用并没有太多冲突的日志记录骗子。

我看过你的pom。问题是jcl-over-slf4j-1.5.8.jar，它包含一些与slf4j 1.6.6不兼容的org.apache.commons.loggin jar。

jcl-over-slf4j-1.5.8.jar被org.jasig.cas 引用

我想尝试用jcl-over-slf4j-1.6.6.jar 代替jcl-over-slf4j-1.5.8.jar

    <dependency>
        <groupId>org.jasig.cas</groupId>
        <artifactId>cas-server-core</artifactId>
        <version>3.5.0</version>
        <exclusions>
            <exclusion>
                <artifactId>jcl-over-slf4j</artifactId>
                <groupId>org.slf4j</groupId>
            </exclusion>
        </exclusions>
    </dependency>
    <dependency>
        <groupId>org.slf4j</groupId>
        <artifactId>jcl-over-slf4j</artifactId>
        <version>1.6.6</version>
    </dependency>

但我不知道cas服务器核心3.5.0是否与jcl-over-slf4j-1.6.6.jar兼容。但在大多数情况下，日志框架的"外部"API比日志桥使用的"内部"API更稳定祝你好运。
