SSM整合-功能模块和接口测试

功能模块

目录结构图：

 1、UserDao

public interface UserDao {
    /**
     * 查询所有用户
     *
     * @return
     */
    @Select("select * from user")
    List<User> findALL();

    /**
     * 通过id查询用户
     * 注解开发@Select("select * from user where userid=#{id}")
     * @param id
     * @return
     */
    @Select("select * from user where userid=#{id}")
    public User findById(int id);

    /**
     * 插入数据
     *
     * @return
     */
    @Insert("insert into user(userid,usercode,username) values(#{userid},#{usercode},#{username})")
    int save(User user);

    /**
     * 更新
     *
     * @return
     */
    @Update("update user set username=#{username},usercode=#{usercode} where userid=#{userid}")
    int update(User user);

    /**
     * 通过id删除
     *
     * @param id
     * @return
     */
    @Delete("delete from user where userid = #{id}")
    int delete(int id);

}

2、User

public class User {
    private Integer userid;
    private String usercode;
    private String userpwd;
    private Boolean isadmin;
    private String username;
    private String telephone;
    private String gender;
    private Integer age;
    private String address;
    private Date createdon;
    private Date updatetime;

    @Override
    public String toString() {
        return "User{" +
                "userid=" + userid +
                ", usercode='" + usercode + '\'' +
                ", userpwd='" + userpwd + '\'' +
                ", isadmin=" + isadmin +
                ", username='" + username + '\'' +
                ", telephone='" + telephone + '\'' +
                ", gender='" + gender + '\'' +
                ", age=" + age +
                ", address='" + address + '\'' +
                ", createdon=" + createdon +
                ", updatetime=" + updatetime +
                '}';
    }

    public Integer getUserid() {
        return userid;
    }

    public void setUserid(Integer userid) {
        this.userid = userid;
    }

    public String getUsercode() {
        return usercode;
    }

    public void setUsercode(String usercode) {
        this.usercode = usercode;
    }

    public String getUserpwd() {
        return userpwd;
    }

    public void setUserpwd(String userpwd) {
        this.userpwd = userpwd;
    }

    public Boolean getIsadmin() {
        return isadmin;
    }

    public void setIsadmin(Boolean isadmin) {
        this.isadmin = isadmin;
    }

    public String getUsername() {
        return username;
    }

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

    public String getTelephone() {
        return telephone;
    }

    public void setTelephone(String telephone) {
        this.telephone = telephone;
    }

    public String getGender() {
        return gender;
    }

    public void setGender(String gender) {
        this.gender = gender;
    }

    public Integer getAge() {
        return age;
    }

    public void setAge(Integer age) {
        this.age = age;
    }

    public String getAddress() {
        return address;
    }

    public void setAddress(String address) {
        this.address = address;
    }

    public Date getCreatedon() {
        return createdon;
    }

    public void setCreatedon(Date createdon) {
        this.createdon = createdon;
    }

    public Date getUpdatetime() {
        return updatetime;
    }

    public void setUpdatetime(Date updatetime) {
        this.updatetime = updatetime;
    }
}

3、UserService

@Transactional
public interface UserService {
    /**
     * 查询所有用户
     *
     * @return
     */
    List<User> findALL();

    /**
     * 通过id查询用户
     * @param id
     * @return
     */
    public User findById(int id);

    /**
     * 插入数据
     *
     * @return
     */
    int save(User user);

    /**
     * 更新
     *
     * @return
     */
    int update(User user);

    /**
     * 通过id删除
     *
     * @param id
     * @return
     */
    int delete(int id);

}

4、UserServiceImpl

Service
public class UserServiceImpl implements UserService {

    @Autowired
    private UserDao userDao;

    @Override
    public List<User> findALL() {

        return userDao.findALL();
    }

    @Override
    public User findById(int id) {
        return userDao.findById(id);
    }

    @Override
    public int save(User user) {
        return userDao.save(user);
    }

    @Override
    public int update(User user) {
        return userDao.update(user);
    }

    @Override
    public int delete(int id) {
        return userDao.delete(id);
    }
}

5、UserController

@RestController
@RequestMapping("/users")
public class UserController {
    @Autowired
    private UserService userService;

    @GetMapping
    public List<User> findALL() {
        return userService.findALL();
    }

    @GetMapping("/{id}")
    public User findById(@PathVariable int id) {
        return userService.findById(id);
    }

    @PostMapping
    public int save(@RequestBody User user) {
        return userService.save(user);
    }

    @PutMapping
    public int update(@RequestBody User user) {
        return userService.update(user);
    }

    @DeleteMapping("/{id}")
    public int delete(@PathVariable int id) {
        return userService.delete(id);
    }
}

接口测试

业务层接口测试

写测试类：

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(classes = SpringConfig.class)
public class UserServiceTest {
    @Autowired
    UserService userService;

    @Test
    public void testFindById(){
        System.out.println(userService.findById(10));
    }
    @Test
    public void testFindAll(){
        System.out.println(userService.findALL());
    }
}

运行结果：

User{userid=10, usercode='admin11', userpwd='admin', isadmin=true, username='admin11', telephone='null', gender='null', age=null, address='null', createdon=Sun May 23 22:22:33 CST 2021, updatetime=Sun May 23 22:22:33 CST 2021}

表现层接口测试

这里调的是findAll接口，用的是REST风格
