- username=#{username},password=#{password} where id=#{id}
- </update>
- <delete id="deleteUser" parameterType="int">
- delete from user where

- </delete>
- </mapper>
7、User实体的写法
- public class User implements Serializable {
- private static final long serialVersionUID = -4415990281535582814L;
- private Integer id;
- private String username;
- private String password;
- 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;
- }
- @Override
- public String toString() {
- return "User [id=" + id + ", password=" + password + ", username=" + username + "]";
- }
- @Override
- public int hashCode() {
- final int prime = 31;
- int result = 1;
- result = prime * result + ((id == null) ? 0 : id.hashCode());
- return result;
- }
- @Override
- public boolean equals(Object obj) {
- if (this == obj)
- return true;
- if (obj == null)
- return false;
- if (getClass() != obj.getClass())
- return false;
- User other = (User) obj;
- if (id == null) {
- if (other.id != null)
- return false;
- } else if (!id.equals(other.id))
- return false;
- return true;
- }
- }
8、UserDao的写法
- public interface UserDao {
- public abstract void insertUser(User user);
- public abstract void updateUser(User user);
- public abstract void deleteUser(Integer userId);
- public abstract User findUserByid(Integer userId);
- public abstract List<User> findAll();
- public abstract User userLogin(User user);
- }
9、UserDao的实现
- @Repository
- public class UserDaoImpl implements UserDao {
- private final String INSERT_USER = "insertUser";
- private final String UPDATE_USER = "updateUser";
- private final String DELETE_USER = "deleteUser";
- private final String FIND_USER_BYID = "findUserById";
- private final String SELECT_ALL_USER = "selectAllUser";
- private final String USER_LOGIN = "userLogin";
- @Autowired
- private SqlSessionTemplate sqlSessionTemplate;
- public void insertUser(User user) {
- sqlSessionTemplate.insert(INSERT_USER, user);
- }
- public void updateUser(User user) {
- sqlSessionTemplate.update(UPDATE_USER, user);
- }
- public void deleteUser(Integer userId) {
- sqlSessionTemplate.delete(DELETE_USER, userId);
- }
- public User findUserByid(Integer userId) {
- return sqlSessionTemplate.selectOne(FIND_USER_BYID, userId);
- }
- public List<User> findAll() {
- return sqlSessionTemplate.selectList(SELECT_ALL_USER);
- }
- public User userLogin(User user) {
- return sqlSessionTemplate.selectOne(USER_LOGIN, user);
- }
- }
10、UserService接口
- public interface UserService {
- // 添加用户
- public abstract void addUser(User user);
- public abstract void updateUser(User user);
- public abstract void deleteUser(Integer userId);
- public abstract User findUserById(Integer userId);
- public abstract List<User> findAllUser();
- public abstract User login(User user);
- }
11、UserService接口的实现
- @Service
- @Transactional
- public class UserServiceImpl implements UserService {
- @Autowired
- private UserDao userDao;
- // 添加用户
- public void addUser(User user) {
- userDao.insertUser(user);
- }
- // 更新用户
- public void updateUser(User user) {
- userDao.updateUser(user);
- }
- public void deleteUser(Integer userId) {
- userDao.deleteUser(userId);
- }
- public User findUserById(Integer userId) {
- return userDao.findUserByid(userId);
- }
- public List<User> findAllUser() {
- return userDao.findAll();
- }
- public User login(User user) {
- return userDao.userLogin(user);
- }
- }
12、配置Struts2

- <constant name="struts.configuration.xmlreload" value="true"/>
- <!-- 当struts配置文件修改时是否自动加载 -->
- <constant name="struts.devMode" value="true"/>
- <!-- 开发模式下打印详细的错误信息 -->
- <constant name="struts.ui.theme" value="xhtml"/>
- <package name="user" namespace="/user" extends="struts-default">
- <action name="user_*" class="userAction" method="{1}">
- <result name="success" type="redirectAction">user_queryAllUser.action</result>
- <result name="input">/index.jsp</result>
- <result name="userList">/userList.jsp</result>
- <result name="addUser">/userAdd.jsp</result>

- }
- public String login() {
- if (user != null) {
- User user2 = userService.login(user);
- if (user2 != null) {
- return SUCCESS;
- }
- }
- this.addFieldError("user.username", "用户名或密码错误!");
- return INPUT;
- }
- public String addUI() {
- return "addUser";
- }
- public String updateUI() {
- user = userService.findUserById(user.getId());
- return "updateUser";
- }
- public String add() {
- userService.addUser(user);
- return SUCCESS;

- return SUCCESS;
- }
- public String update() {
- userService.updateUser(user);
- return SUCCESS;
- }
- public User getUser() {
