标签： java spring spring-mvc tomcat

我在Tomcat上使用Spring MVC。当我尝试启动tomcat时，我得到了这个例外：

WARNING: Exception encountered during context initialization - cancelling refresh attempt

我已经在Eclipse项目和Web App Libraries中链接了Gradle依赖项，这似乎是相同的。两者都在版本4.2.1.RELEASE

中有Spring

Tomcat8 / lib中没有Spring库。

在Eclipse中，Tomcat已经在版本4.2.1.RELEASE中链接了Spring库（在Tomcat 8概述 - ＆gt;启动配置 - ＆gt;源代码下找到）

我是Spring的新手，我已经尝试了谷歌搜索解决方案几个小时没有运气。谢谢你的帮助。

答案 0 :(得分：2)

我已经通过清理项目，清理Tomcat和清理Tomcat Work目录来解决了这个问题。

无论如何，我的代码还有另一个问题：

public class ServiceManager {

    private static volatile ServiceManager instance;

    public final JiraService jira;
    public final GitService git;
    public final JenkinsService jenkins;

    @Autowired
    private ServiceConfiguration conf;

    private ServiceManager() {
        this.jira = new JiraServiceSynchronousImpl(conf);
        this.git = new JGitGitServiceImpl(conf);
        this.jenkins = new SimpleJenkinsServiceImpl(conf);
    }

这是错误的，因为Spring没有自动装配字段在构造函数中使用它。我修好了这个：

public class ServiceManager {

    private static volatile ServiceManager instance;

    public final JiraService jira;
    public final GitService git;
    public final JenkinsService jenkins;

    @Autowired
    private ServiceManager(ServiceConfiguration conf) {
        this.jira = new JiraServiceSynchronousImpl(conf);
        this.git = new JGitGitServiceImpl(conf);
        this.jenkins = new SimpleJenkinsServiceImpl(conf);
    }

答案 1 :(得分：1)

我非常怀疑您拥有不同版本的依赖项spring-web和spring-webmvc。检查您的pom.xml并确定您使用的是非常相同版本的所有spring依赖项，然后重试

答案 2 :(得分：1)

在堆栈跟踪中查看此部分：

Caused by: java.lang.NoSuchMethodError: org.springframework.web.bind.annotation.RequestMapping.path()[Ljava/lang/String;

确保您的pom.xml中没有包含不同版本Spring的多个jar文件。
