记录一下Maven整合spring,hibernate,strusts2我程序中出的bug

action类如下

package com.itheima.movenweb.action;

import java.util.List;

import org.apache.struts2.ServletActionContext;
import org.junit.Test;

import com.itheima.movenweb.domain.Dep;
import com.itheima.movenweb.service.Service;
import com.opensymphony.xwork2.ActionSupport;
import com.opensymphony.xwork2.ModelDriven;

public class Action extends ActionSupport {

    private Service service;

    public Service getService() {
        return service;
    }
    public void setService(Service service) {
        this.service = service;
    }
    public String findDepList(){
        System.out.println(1);
        List<Dep> list = service.dolist();
        System.out.println(service);
        ServletActionContext.getRequest().setAttribute("list", list);
        return "success";
    }
    
    

}

serviceImpl如下:

package com.itheima.movenweb.serviceImpl;

import java.util.List;

import org.junit.Test;

import com.itheima.movenweb.dao.Dao;
import com.itheima.movenweb.domain.Dep;
import com.itheima.movenweb.service.Service;

public class ServiceImpl implements Service {
    
    private Dao dao;
    

    public Dao getDao() {
        return dao;
    }


    public void setDao(Dao dao) {
        this.dao = dao;
    }


    @Override
    public List<Dep> dolist() {
        System.out.println(2);
        List<Dep> list = dao.dolist();
        return list;
    }

}

daoImpl如下:

package com.itheima.movenweb.daoImpl;

import java.util.List;

import org.springframework.orm.hibernate5.support.HibernateDaoSupport;

import com.itheima.movenweb.dao.Dao;
import com.itheima.movenweb.domain.Dep;

public class DaoImpl extends HibernateDaoSupport implements Dao{

    @Override
    public List<Dep> dolist() {
        System.out.println(3);
         List<Dep> list = (List<Dep>) this.getHibernateTemplate().find("from Dep");
        return list;
    }
    

}

applicationContext.xml 如下:

<?xml version="1.0" encoding="UTF-8"?>

 	</bean>
 
</beans>
	

  struts.xml 如下:

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE struts PUBLIC
    "-//Apache Software Foundation//DTD Struts Configuration 2.3//EN"
    "http://struts.apache.org/dtds/struts-2.3.dtd">
<struts>
    <package name="default" namespace="/" extends="struts-default">  
    <action name="index" class="depAction" method="findDepList">
    <result name="success">/success.jsp</result>
    </action>             
    </package>
</struts>

还有hibernate的配置文件,我报错的原因和他没有关系,我就不放在这里了;以上的代码是修改后正确的代码;

下面我放入我错误的代码,第一个错误在struts2的配置文件,我将class的配置信息配成了类的全路径,然后报空指针异常,这里class的路径应该写已经配置在applicationContext.xml中的action的id的值

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE struts PUBLIC
	"-//Apache Software Foundation//DTD Struts Configuration 2.3//EN"
	"http://struts.apache.org/dtds/struts-2.3.dtd">
<struts>
    <package name="default" namespace="/" extends="struts-default">  
    <action name="index" class="com.itheima.movenweb.domain.Dep" method="findDepList">
    <result name="success">/success.jsp</result>
    </action>  	   	
    </package>
</struts>

  然后又出了一个问题:如下

我的action中的输出语句输出了,但是我的数据库没有连接上,我去查询我的数据库,发现我的数据库名字是“mavenwebtest11;”  对,你没有看错,我的数据库名字多加了“;”我发现我在创建数据库后本来是想加上英文状态的结束符号,结果加成了中文的结束符号,然后就被一起写进了数据库的名字中,大写的尴尬呀,作为我的第一篇博客,谨以此来激励自己不断学习,不断成长
