2. spring配置文件和struts配置文件（struts的配置文件不写路径的话默认是图中这个位置，一般这个位置存放xml配置）

这里写图片描述

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE struts PUBLIC
    "-//Apache Software Foundation//DTD Struts Configuration 2.1.7//EN"
    "http://struts.apache.org/dtds/struts-2.1.7.dtd">

<struts>

      <!-- 将默认的.action扩展名改为.do -->
    <constant name="struts.action.extension" value="do"></constant>

    <!-- extends继承框架内部struts-default -->
    <package name="demo1" extends="struts-default" >
        <!-- name指定为请求名;class指定action类;method指定action方法名，不写默认为execute -->
        <action name="hello" class="ohMyGod" method="HaHaHa">
            <!-- name对应action方法返回结果;type指定result组件类型 -->
            <result name="success" type="dispatcher">
                /WEB-INF/hello.jsp
            </result>
        </action>

        <action name="list" class="songTieDan" method="HaHaHa">

        </action>

        <action name="login" class="cn.xdl.action.DunChunLiang">
            <result>
                /login.jsp
            </result>
        </action>

    </package>

    <package name="demo2" extends="struts-default"  namespace="/user">
        <action name="list" class="login" method="execute">
            <result name="success" type="dispatcher">
            /ok.jsp
            </result>
            <result name="error" type="dispatcher">
            /login.jsp
            </result>
        </action>
    </package>
</struts>

这里写图片描述

3.Dao接口和实体类注解和详情代码

  • Dao接口实现类
@Repository("examDao")
public class ExamPaperDaoImpl implements ExamPaperDao {
@Resource
private JdbcTemplate Template;
    @Override
    public List getAll() {
        return Template.query("select * from exam_paper", new ExamPaperMapper());
    }

    @Override
    public ExamPaper getByPaperId(int questionId) {
        Object[] obj ={questionId};
        return  Template.queryForObject("select * from exam_paper where question_id=? ",obj  ,new ExamPaperMapper());
    }

}
  • controller实体类
/**
 * 1.接收请求处理，请求处理方法public String execute(){...}
 * 2.响应处理结果，利用请求处理方法的返回值String,含义是result名<result name="xxx"> 
 * 3.接收请求参数，利用属性接收,属性名与参数key保持一致（setter/getter）
 */
@Controller
@Scope("prototype")
public class OhMyGod{

    private String msg;//jsp采用${msg}获取值
    private String name;//接收name=xxx值


    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public String getMsg() {
        return msg;
    }

    public void setMsg(String msg) {
        this.msg = msg;
    }

    public String HaHaHa(){
        System.out.println("执行了HelloAction处理");
        if(name != null && !"".equals(name)){
            msg = "Hello "+name;
        }else{
            msg = "宋铁蛋你是不是傻";
        }

        return "success";
    }
