簡單許可權系統基於shiro-springmvc-spring-mybatis(學習筆記 1)
阿新 • • 發佈：2019-01-25
一個簡單的許可權管理系統，實現使用者、許可權、資源的增刪改查，這三者之間相互的授權和取消授權，如：一個使用者可以擁有多個許可權並且一個許可權可以擁有多個資源。
系統基於shiro、springmvc、spring、mybatis，使用mysql資料庫。

使用mapper代理開發
SqlMapConfig.xml
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE configuration
PUBLIC "-//mybatis.org//DTD Config 3.0//EN"
"http://mybatis.org/dtd/mybatis-3-config.dtd">
<configuration>
<settings>
<setting name="cacheEnabled" value="false"></setting>
<setting mapper.xml中名稱空間對應相應mapper介面路徑
主鍵返回語句：
<insert id="insert">
<selectKey keyProperty="id" order="AFTER" resultType="long">
SELECT LAST_INSERT_ID();
</selectKey>
insert into user_role(user_id, role_id)
values(#{userId},#{roleId})
</insert>還可以使用<set>、<if>標籤 ：
<update id="updateByPrimaryKeySelective">
update user_role
<set>
<if test="userId != null">
user_id = #{userId}
</if>
<if test="roleId != null">
role_id = #{roleId}
</if>
</set>
where id = #{id}
</update>**<sql>標籤的使用：**
<sql id="Base">
id, name, url, description, icon, pid, seq, status, resourcetype, createdate
</sql>
<select id="findResourceById">
select
<include refid="Base"></include>
from resource where id= #{id};
</select>Dao層測試類：
public class UserRoleMapperTest {
private UserRoleMapper mapper;
@Before
public void setUp() throws Exception {
String resource = "SqlMapConfig.xml";
InputStream config = Resources.getResourceAsStream(resource);
SqlSessionFactory sqlSessionFactory = new SqlSessionFactoryBuilder().build(config);
SqlSession sqlSession = sqlSessionFactory.openSession();
mapper = sqlSession.getMapper(UserRoleMapper.class);
}
@Test
public void testInsert() {
UserRole userRole = new UserRole();
userRole.setRoleId((long) 3);
userRole.setUserId((long) 2);
int i = mapper.insert(userRole);
}spring整合mybatis:
spring-mybatis.xml:

</beans>測試時一直報錯找不到mapper介面中方法在mapper.xml中對應的id,
後將下面配置改動了一下，測試通過——
<bean id="SqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
<!-- 載入mybatis配置 -->
<property name="mapperLocations" value="classpath*:config/mappers/*.xml"></property>
<property name="configLocation" value="classpath:/SqlMapConfig.xml"></property>
<property name="dataSource" ref="DataSource"></property>
</bean>將classpath*:/mappers/*.xml改成了classpath*:config/mappers/*.xmlService層：
applicationContext.xml:
<?xml version="1.0" encoding="UTF-8"?>

<context:component-scan base-package="com.spring.shiro.main.java.service。impl,com.spring.shiro.main.java.mapper"></context:component-scan>
<import resource="spring/spring-mybatis.xml"></import>
</beans>使用註解開發，service實現類：
（呼叫mapperBean,組合使用mapper操作資料庫的方法實現業務邏輯處理）
@Service
public class UserServiceImpl implements UserService {
public static Logger LOGGER = LoggerFactory.getLogger(UserServiceImpl.class);
private ApplicationContext apl = new ClassPathXmlApplicationContext("applicationContext.xml");
//@Autowired
private UserMapper userMapper = (UserMapper) apl.getBean("userMapper");
@Resource
private UserRoleMapper userRoleMapper;
@Override
public User findUserByLoginName(String username) {
return userMapper.findUserByLoginName(username);
}
@Override
public User findUserById(Long id) {
return userMapper.findUserById(id);
}
@Override
public void findUserGrid(PageInfo pageInfo) {
pageInfo.setRows(userMapper.findUserPageCondition(pageInfo));
pageInfo.setTotal(userMapper.findUserPageCount());
}
@Override
public void addUser(UserVo userVo) {
User user = new User();
try{
PropertyUtils.copyProperties(user, userVo);
}catch(Exception e) {
LOGGER.error("類轉換異常：{}", e);
throw new RuntimeException("類轉換異常：{}",e);
}
System.out.println(user);
userMapper.insert(user);
Long id = user.getId();
String[] roles = userVo.getRoleIds().split(",");
UserRole userRole = new UserRole();
for(String roleId : roles) {
userRole.setUserId(id);
userRole.setRoleId(Long.valueOf(roleId));
userRoleMapper.insert(userRole);
}
}
@Override
public void updateUserPwdById(Long userId, String pwd) {
userMapper.updateUserPasswordById(userId, pwd);
}
@Override
public UserVo findUserVoById(Long id) {
return userMapper.findUserVoById(id);
}
@Override
public void updateUser(UserVo userVo) {
User user = new User();
try{
PropertyUtils.copyProperties(user, userVo);
}catch(Exception e) {
LOGGER.error("類轉換異常：{}", e);
throw new RuntimeException("類轉換異常：{}",e);
}
userMapper.updateUser(user);
Long id = userVo.getId();
List<UserRole> userRoles = userRoleMapper.findUserRoleByUserId(id);
if(userRoles != null && (!userRoles.isEmpty())) {
for(UserRole userRole : userRoles) {
userRoleMapper.deleteById(userRole.getId());
}
}
String[] roleIds = userVo.getRoleIds().split(",");
UserRole userRole = new UserRole();
for(String roleId : roleIds) {
userRole.setId(id);
userRole.setRoleId(Long.parseLong(roleId));
userRoleMapper.insert(userRole);
}
}
@Override
public void deleteUserById(Long id) {
int delete = userMapper.deleteById(id);
if(delete != 1) {
throw new RuntimeException("刪除使用者失敗！");
}
}
測試時，@Autowired註解不能自動裝載mapperBean,mapperBean中始終為空值。最終改成了從容器中獲取mapperBean。
@Autowired
private UserMapper userMapper;改成了如上
private ApplicationContext apl = new ClassPathXmlApplicationContext("applicationContext.xml");
//@Autowired
private UserMapper userMapper = (UserMapper) apl.getBean("userMapper");service測試類(匯入了spring的Junit測試環境)：
@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations={"classpath:applicationContext.xml"})
public class UserServiceImplTest extends AbstractJUnit4SpringContextTests{
@Before
public void setUp() throws Exception {
}
@Test
public void test() {
UserVo userVo = new UserVo();
userVo.setAge(3);
userVo.setCreatedate(new Date());
userVo.setId((long) 3);
userVo.setLoginName("abcss");
userVo.setName("aaa");
userVo.setPassword("123");
userVo.setPhone("123466");
userVo.setRoleIds("4,6,7");
userVo.setSex(1);
userVo.setStatus(3);
userVo.setUserType(3);
userVo.setOrganizationId(2);
UserServiceImpl userServiceImpl = new UserServiceImpl();
userServiceImpl.addUser(userVo);
}
@Test
public void testMapper() {
ApplicationContext apl = new ClassPathXmlApplicationContext("applicationContext.xml");
UserMapper userMapper = (UserMapper) apl.getBean("userMapper");
User user = new User();
user.setAge(12);
user.setCreatedate(new Date());
user.setLoginName("abcd");
user.setName("name");
user.setOrganizationId(2);
user.setPassword("123456");
user.setPhone("136");
user.setSex(1);
user.setStatus(3);
user.setUserType(2);
int i = userMapper.insert(user);
}
}
