Question

我正在尝试将Spring依赖注入添加到我的项目中，因为我将Spring集成所需的所有内容添加到我的项目中，Web项目无法部署... 为什么我认为它与我的Spring配置有关？好吧，在添加任何弹簧配置之前，Vaadin gui，servlet DEPLOYED完美，以及泽西休息网络服务......

现在我在尝试运行时遇到此错误：

我尝试删除了jersey web服务servlet部分，但它仍然无法加载vaadin前端servlet，如果你需要没有jersey的错误，我可以发布它，但我认为没有必要。

如果我删除泽西岛部分，我明白了：

webservice类如下所示：

    package com.nortal.pirs.webservices;

import javax.ws.rs.GET;
import javax.ws.rs.Path;
import javax.ws.rs.PathParam;
import javax.ws.rs.Produces;
import javax.ws.rs.core.MediaType;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.annotation.Qualifier;
import org.springframework.stereotype.Service;

import com.nortal.pirs.businesslogic.factories.ControllerFactoryProvider;
import com.nortal.pirs.businesslogic.interfaces.UserManagerInterface;

@Path("/emailcheck/{emailAddress}")
public class EmailCheckService {

    //@Autowired
    //@Qualifier("UserManager")
    private UserManagerInterface userManager = ControllerFactoryProvider.getInstance().createUserManager();

    @GET
    @Produces(MediaType.APPLICATION_JSON)
    public String emailExists(@PathParam("emailAddress") String email) {
        if (userManager.emailExists(email)) {
            return "true";
        } else {
            return "false";
    }
    }

    public void setUserManager(UserManagerInterface userManager) {
        this.userManager = userManager;
    }
}

有人遇到过这种问题吗？我以为是因为我在配置中添加了spring，但是即使我将其删除它似乎也不起作用，实际上web.xml中的任何内容似乎都无法正常工作......也许它与Tomcat有关？我正在使用在Eclipse中配置的Tomcat 7。我试过清理它，但它似乎没有帮助。我真的很困惑。

Answer 1

Jersey找不到任何可以作为Jersey RESTful Web服务执行的类。

检查：

com.sun.jersey.config.property.packages中是否遗漏了web.xml - 似乎没问题。
com.sun.jersey.config.property.packages param的值是否丢失或无效 - 我无法分辨。
是否至少有一个POJO有一个用@Path注释的方法 - 我不知道。
如果此例外的many Google hits可以为您提供更多帮助。

Answer 2

您可以验证您的Resource类是否位于此文件包（com.nortal.pirs.webservices）中，如您的web.xml中所定义的那样？您的服务器日志指示无法找到资源类。假设该包包含Resource类，服务器日志将显示类的列表。我有一个同时使用Spring和Jersey的项目没有问题。

也许，您可能希望在web.xml中为servlet禁用servlet-mapping和PirsVaadinFrontend，并首先调试Jersey错误。这里有2个不同的错误，我不能确定是否是导致其他问题的一个问题，或者是否有2个独立的问题。

Spring配置问题 - 无法加载应用程序类
