小伙伴儿们，大家好！今天给大家分享一个SSM项目实战系列——cms系统；第一篇是SSM框架搭建，后续会持续更新，敬请期待！

思维导图：

1，配置文件引入

1.1，创建Maven项目，添加依赖；

pom.xml文件：

这里有的jar包还需要我们手动导入：

导入之后记得添加jar包：

1.2，Resources资源文件；

我们在main目录下新建两个文件夹，分别是java和resources，并把cms标记为Sources目录，resources标记为Resources目录；

导入5个配置文件：分别是Spring，SpringMVC，MyBatis和日志相关的配置文件；

ManagerMapper.xml（注意文件路径）：

<?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">
<mapper namespace="com.cms.dao.ManagerDao">

 <resultMap type="Manager" id="ManagerResult">
  <result property="id" column="id"/>
  <result property="userName" column="userName"/>
  <result property="password" column="password"/>
 </resultMap>

</mapper>

 <!-- 使用注解的包，包括子集 -->
 <context:component-scan base-package="com.java.controller" />
</beans>

2，创建数据库；

创建数据库db_cms，并加上一张表t_manager：

我们添加一条数据进去即可；

3，项目结构搭建；

dao数据访问层：ManagerDao接口：

package com.cms.dao;

/**
 * 管理员Dao接口
 * @author user
 *
 */
public interface ManagerDao {

}

这里要对应上文的ManagerMapper.xml文件，形成映射，这是MyBatis核心文件；

entity实体层：Manager实体类：

package com.cms.entity;

/**
 * 管理员实体
 * @author user
 *
 */
public class Manager {

    private Integer id; // 编号
    private String userName; // 用户名
    private String password; // 密码

    public Integer getId() {
        return id;
    }
    public void setId(Integer id) {
        this.id = id;
    }
    public String getUserName() {
        return userName;
    }
    public void setUserName(String userName) {
        this.userName = userName;
    }
    public String getPassword() {
        return password;
    }
    public void setPassword(String password) {
        this.password = password;
    }

}

这里就是一个与数据库表t_manager相对应的实体类；还有与mybatis-config.xml相对应，里面的别名就是实体层；

service事务层：ManagerService接口：

package com.cms.service;

/**
 * 管理员Service接口
 * @author user
 *
 */
public interface ManagerService {

}

ManagerServiceImpl实现类：

package com.cms.service.impl;

import javax.annotation.Resource;

import org.springframework.stereotype.Service;

import com.cms.dao.ManagerDao;
import com.cms.service.ManagerService;

/**
 * 管理员Service实现类
 * @author user
 *
 */
@Service("managerService")
public class ManagerServiceImpl implements ManagerService{

 @Resource
 private ManagerDao managerDao;
}

这属于事务层，通过继承具体实现该类；

controller控制层：ManagerController类：

package com.cms.controller;

import javax.annotation.Resource;

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;

import com.cms.service.ManagerService;

/**
 * 管理员Controller层
 * @author user
 *
 */
@Controller
@RequestMapping("/manager2")
public class ManagerController {

    @Resource
    private ManagerService managerService;
}

具体的控制层，先搭个框架；

Shiro认证层：自定义MyRealm类：

package com.cms.realm;

import org.apache.shiro.authc.AuthenticationException;
import org.apache.shiro.authc.AuthenticationInfo;
import org.apache.shiro.authc.AuthenticationToken;
import org.apache.shiro.authz.AuthorizationInfo;
import org.apache.shiro.realm.AuthorizingRealm;
import org.apache.shiro.subject.PrincipalCollection;

/**
 * 自定义Reaml
 * @author user
 *
 */
public class MyRealm extends AuthorizingRealm{

    @Override
    protected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principals) {
        // TODO Auto-generated method stub
        return null;
    }

    @Override
    protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken token) throws AuthenticationException {
        // TODO Auto-generated method stub
        return null;
    }

}
