Java SpringMVC Autowiring BeanCreationException

Question

我在 Tomcat 上使用 Spring MVC。当我尝试启动 tomcat 时出现此异常:

WARNING: Exception encountered during context initialization - cancelling refresh attempt

我在 Eclipse 项目和 Web 应用程序库中链接了 Gradle 依赖项，这似乎是相同的。两者都有 4.2.1.RELEASE 版本的 Spring

Tomcat8/lib 中没有Spring 库

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

我是 Spring 的新手，我已经尝试谷歌搜索解决方案几个小时但没有成功。感谢您的帮助。

我已经通过清理项目、清理 Tomcat 和清理 Tomcat 工作目录解决了这个问题。

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 不会 Autowiring 字段以在构造函数中使用它。我用这个修复了它:

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);
    }
