maven下配置ssm框架

前提环境：maven环境已经搭建
jdk版本:jdk1.8.0_60
toncat版本:apache-tomcat-8.0.24
maven版本：apache-maven-3.3.9
ok,现在开始。
1.建立maven web项目项目。
在pom.xml添加依赖：

    </bean>

    <!-- 6、 使用声明式事务 transaction-manager：引用上面定义的事务管理器 -->
    <tx:annotation-driven transaction-manager="txManager" />

</beans>  

database.properties:

jdbc.properties:

jdbc.driverClassName=com.mysql.jdbc.Driver  
jdbc.url=jdbc:mysql://localhost:3306/tccp  
jdbc.username=root  
jdbc.password=123456

4.配置mybatis的配置文件mybatis-conf.xml

<?xml version="1.0" encoding="UTF-8"?>    
<!DOCTYPE configuration PUBLIC "-//mybatis.org//DTD Config 3.0//EN"

到此，配置文件就算是完了，
然后就是，
实体类：Use.java

package com.tc.tccp.core.entity;

public class User {
    private String id;
     private String username;
     private String password;


     public String getId() {
        return id;
    }
    public void setId(String id) {
        this.id = id;
    }
    public String getUsername() {
      return username;
     }
     public String getPassword() {
      return password;
     }

     public void setUsername(String username) {
      this.username = username;
     }
     public void setPassword(String password) {
      this.password = password;
     }

     public User(String username, String password) {
      super();
      this.username = username;
      this.password = password;

     }
     public User() {
      super();
     }


    }

各层间：dao层：
UserDao.java:

package com.tc.tccp.web.dao;

import java.util.List;
import java.util.Map;

import com.tc.tccp.core.entity.User;

public interface UserDao {

    public boolean insert(User test);
    public User find(String id);
    public List<User> findAll();
    public boolean delete(String id);
    public boolean update(User us);
    public User findbyusernameandpassword(Map<String,String> map);
}

UserDao.xml:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN" 
"http://mybatis.org/dtd/mybatis-3-mapper.dtd">
<!-- 
    namespace：必须与对应的接口全类名一致

 -->
 <mapper namespace="com.tc.tccp.web.dao.UserDao">

    <insert id = "insert" parameterType = "User">
        insert into user(id, username,password) values(#{id}, #{username},#{password})
    </insert>

    <select id = "find" parameterType = "java.lang.String" resultType="User">
        select * from user where id = #{id}
    </select>

    <select id = "findAll" resultType="User">
        select * from user
    </select>

    <select id = "findbyusernameandpassword" resultType="User">
        select * from user where username=#{username} and password=#{password}
    </select>


    <delete id = "delete" parameterType = "java.lang.String">
        delete from user where id = #{id}
    </delete>

    <update id = "update" parameterType = "User" >
        update user set username = #{username},password=#{password}where id = #{id}
    </update>
 </mapper>

service层：
service接口UserService:

package com.tc.tccp.web.service;

import java.util.List;
import java.util.Map;

import com.tc.tccp.core.entity.User;


public interface UserService {
    public User insert(User test);
    public User find(String id);
    public List<User> findAll();
    public boolean delete(String id);
    public User update(User test);
    public User findbyusernameandpassword(Map<String,String> map);
}

serviceimpl层实现类：UserServiceImpl:

package com.tc.tccp.web.service.impl;

import java.sql.SQLException;
import java.util.List;
import java.util.Map;

import org.springframework.beans.factory.annotation.Autowired;

import com.tc.tccp.core.exception.EntityException;
import com.tc.tccp.web.dao.UserDao;
import com.tc.tccp.web.service.UserService;

@Service
@Transactional
public class UserServiceImpl implements UserService{

    String emp=null;

    @Autowired
    private UserDao userDao;



    @Override
    public User insert(User us) {
        try{
             userDao.insert(us);
             return userDao.find(us.getId());
        }catch(EntityException e){
             throw new EntityException("查找用户错误",e);
        }


    }

    @Override
    public User find(String id) {

        User user = null;
        try {
             user=userDao.find(id);

        }catch(EntityException e){
             throw new EntityException("查找用户错误",e);
        }

        return user;


    }

    @Override
    public List<User> findAll() {
        try{
             return userDao.findAll();

        }catch(EntityException e){
             throw new EntityException("Error！ when insert the entity",e);
        }
    }

    @Override
    public boolean delete(String id) {
        try{
             return userDao.delete(id);

        }catch(EntityException e){
             throw new EntityException("Error！ when insert the entity",e);
        }
    }

    @Override
    public User update(User us) {
        try{
             userDao.update(us);
             return userDao.find(us.getId());
        }catch(EntityException e){
             throw new EntityException("Error！ when insert the entity",e);
        }


    }

    @Override
    public User findbyusernameandpassword(Map<String ,String > map){
        try{
         User us=userDao.findbyusernameandpassword(map);
         return userDao.find(us.getId());
         }catch(EntityException e){
             throw new EntityException("Error！ when insert the entity",e);
        }
    }

}

好了剩下的login.jsp页面自己不全
项目目录：

注意：项目路径中有shiro的配置信息及导入的类，文档中没加shiro,不要创建带shiro的路径。
