Answer 2

您的Tomcat已配置为使用Spring的类加载器检测框架，但类路径中缺少Spring。

您需要删除该检测配置，或将Spring添加到类路径中。

Answer 3

似乎其中一个Spring jar不在你的类路径上。

Answer 4

这个问题很难回答而不需要更多细节......我在不同情况下遇到了这个（或类似的）错误，其中一个问题刚刚解决了。

如果您使用Eclipse的“Run as / Run on Server”命令/菜单运行应用程序，那么您可以尝试手动将spring-instrument-tomcat-.jar添加到Tomcat的安装home / lib /目录中，然后再试一次;或者（如果你实际上不需要LTW或检测） - 检查你的项目中是否有loaderClass =“org.springframework.instrument.classloading.tomcat.TomcatInstrumentableClassLoader”.webapp / META-INF / context.xml并将其删除。

如果您实际上正在使用Maven并从eclipse运行“Run As / Maven ...”（那么 - tomcat6：run命令;也可以从控制台执行），那么这是一个不同的故事。以下POM配置适用于在独立tomcat上部署（如果您已按上述方法添加了spring JAR）和嵌入式tomcat： ...

<build>
    <plugins>
        <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-war-plugin</artifactId>
            <version>2.2</version>
            <configuration>
                <webResources>
                    <resource>
                        <targetPath>META-INF</targetPath>
                        <directory>src/main/config</directory>
                        <includes>
                            <include>context.xml</include>
                        </includes>
                    </resource>
                </webResources>
            </configuration>
        </plugin>
        <plugin>
            <groupId>org.apache.tomcat.maven</groupId>
            <artifactId>tomcat6-maven-plugin</artifactId>
            <version>2.0</version>
            <configuration>
                <port>8080</port>
                <path>/</path>                  
                <update>true</update>               
                <classLoaderClass>org.springframework.instrument.classloading.tomcat.TomcatInstrumentableClassLoader</classLoaderClass>
            </configuration>
            <dependencies>
                <dependency>
                    <groupId>org.springframework</groupId>
                    <artifactId>spring-instrument-tomcat</artifactId>
                    <version>${spring.version}</version>
                </dependency>
            </dependencies>
        </plugin>
    </plugins>
</build>

注意：TomcatInstrumentableClassLoader和META-INF / context.xml文件与tomcat6-maven-plugin（当context.xml文件不在src / main / webapp / META-INF / context.xml中时有效），所以我不得不把它移到src / main / config然后让maven-war-plugin来处理它。

干杯， IR。
