好吧，我正在尝试将Spring依赖注入添加到我的项目中，自从我将Spring集成所需的所有东西都添加到我的项目中后，Web项目无法部署...为什么我认为它与我的Spring配置有关? 在添加任何 Spring 配置之前，Vaadin gui、servlet 已完美部署，jersey rest web 服务也是如此......

现在我在尝试运行它时遇到了这个错误：

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

如果我删除 Jersey 部分，我会得到：

网络服务类如下所示：

    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？我认为这是因为我在配置中添加了 spring，但是即使我删除它似乎也不起作用，实际上 web.xml 中的任何内容现在似乎都不起作用......也许是 Tomcat 的问题？我正在使用在 Eclipse 中配置的 Tomcat 7。我尝试清洁它，但它似乎也没有帮助。我真的很困惑。

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

查看：

  • 您的 -是否com.sun.jersey.config.property.packages缺少web.xml- 似乎没问题。
  • param 的值com.sun.jersey.config.property.packages是丢失还是无效 - 我无法判断。
  • 是否至少有一个 POJO 有一个带有注释的方法@Path- 我不知道。
  • 如果这个例外的许多谷歌点击可以帮助你进一步。

您能否验证您的Resource类是否位于com.nortal.pirs.webservicesweb.xml 中定义的这个包 ( ) 中？您的服务器日志表明找不到资源类。假设该包是否包含Resource类，服务器日志将显示类列表。我有一个项目同时使用 Spring 和 Jersey 没有问题。

也许，您可能想在 web.xml 中禁用servlet和servlet-mappingforPirsVaadinFrontend并首先调试 Jersey 错误。您在这里有 2 个不同的错误，我不能确定是一个问题导致了另一个问题，还是您有 2 个独立的问题。
