我在部署代码时遇到以下异常

 Caused by: org.springframework.beans.factory.NoSuchBeanDefinitionException: No unique bean of type [com.belk.api.adapter.contract.Adapter] is defined: expected single matching bean but found 2: [endeca, solar]

我有3个不同的项目,一个是Common,第二个是Adapter,第三个是Service.适配器依赖于Common,而Service依赖于Adapter.这三个都是maven项目.现在在我的Common项目中,我有一个名为CommonAdapter.java的接口

 public interface CommonAdapter {
    List service() ;
}

我在同一个项目中有一个名为AdapterFactory.java的类(i,e Common)

@Component
public class AdapterFactory {
    @Autowired
    Adapter adapter;
    public Adapter getAdapter(String adapterName){
        return adapter;
    }

}   
    <context:component-scan base-package="com.test.api" />
    <bean
        class="org.springframework.beans.factory.config.ServiceLocatorFactoryBean"
        id="adapterFactory">
        <property name="serviceLocatorInterface" value="com.test.api.adapter.manager.AdapterFactory">
        </property>
    </bean>

现在在我的Adapter Project中,我有CommonAdapter.java的实现类,一个是EndecaAdapetr.java,另一个是SolarAdapter.java

@Component("endeca")
public class EndecaAdapter implements Adapter {
    List service() { …

试图整合hibernate和spring,我遇到了这个错误

严重:上下文初始化失败 org.springframework.beans.factory.BeanCreationException:创建名为' org.springframework.web.servlet.mvc.annotation.DefaultAnnotationHandlerMapping'的bean时出错:bean的初始化失败; 嵌套异常是java.lang.IllegalStateException:无法将处理程序' org.me.spring.hib.school.web.SchoolController#0' 映射到URL路径[ /allschools]:已经有类型[class org.me.spring.hib.school.web.SchoolController]映射的处理程序.

我的控制器看起来像

package org.me.spring.hib.school.web;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import org.me.spring.hib.school.dao.SchoolDAO;
import org.springframework.stereotype.Controller;
import org.springframework.ui.ModelMap;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.servlet.ModelAndView;

@Controller
public class SchoolController {
    private SchoolDAO schoolDao;

    public SchoolDAO getSchoolDao() {
        return schoolDao;
    }

    public void setSchoolDao(SchoolDAO schoolDao) {
        this.schoolDao = schoolDao;
    }
        @RequestMapping("/allschools")
    public ModelAndView showAllSchools(HttpServletRequest request,HttpServletResponse response) throws Exception{
        if(this.schoolDao ==null){
            System.out.println("this.schoolDao is null");
        }
        ModelMap modelMap = new ModelMap();
        modelMap.addAttribute("schoolsList", this.schoolDao.getAllSchools());
        return new …
