com.xxx.model.userManagement.Admin
package com.xxx.model.userManagement; /** * 管理员 */ public class Admin { private int id; private String username; private String password; public int getId() { return id; } public void setId(int 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; } }
com.xxx.mapper.userManagement.AdminMapper
package com.xxx.mapper.userManagement; import org.apache.ibatis.annotations.Insert; import org.apache.ibatis.annotations.Param; import org.apache.ibatis.annotations.Result; import org.apache.ibatis.annotations.Results; import org.apache.ibatis.annotations.Select; import com.xxx.model.userManagement.Admin; /** * 管理员Mapper */ public interface AdminMapper { @Insert("INSERT INTO userinfo(username, password) VALUES(#{username},#{password})") public int insertAdmin(Admin admin); @Select("SELECT * FROM userinfo WHERE username = #{username} AND password = #{password}") @Results(value = { @Result(id = true, column = "id", property = "id"), @Result(column = "username", property = "username"), @Result(column = "password", property = "password") }) public Admin selectAdmin(@Param("username") String username, @Param("password") String password); }

package com.xxx.service.userManagement; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.stereotype.Service; import com.xxx.dao.userManagement.AdminDao; import com.xxx.model.userManagement.Admin; /** * 管理员service */ @Service public class AdminService { @Autowired private AdminDao adminDao; public boolean register(Admin admin){ return adminDao.register(admin); } public Admin login(String username, String password) { return adminDao.login(username, password); } }
代码很简单,与之前的基本一样,只是名字换了而已。
值得注意的是包名:com.xxx.mapper.userManagement而非com.xxx.userManagement.mapper。
