springboot-jpa-thymeleaf
上次说道springboot整合持久层mybatis，今天换一个持久层进行整合，并且配合一款j模版引擎thymeleaf实现一个登录的功能
jpa简介
JPA是Java Persistence API的简称，中文名Java持久层API，是JDK 5.0注解或XML描述对象－关系表的映射关系，并将运行期的实体对象持久化到数据库中，Jpa是一种规范，而持久层的老框架Hibernate是它的一种实现其实，jpa代码运用中更简洁，但是jpa与mybatis到底哪个更好更适合还要根据具体的开发情景。
thymeleaf简介
Thymeleaf是一款用于渲染XML/XHTML/HTML5内容的模板引擎。类似JSP，Velocity，FreeMaker等，它也可以轻易的与Spring MVC等Web框架进行集成作为Web应用的模板引擎。与其它模板引擎相比，Thymeleaf最大的特点是能够直接在浏览器中打开并正确显示模板页面，而不需要启动整个Web应用。支持el以及jstl等
整合过程
利用maven快速创建springboot的工程（前面有介绍）
打开pom.xml引入相应的依赖
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

紧接着配置application.properties：
spring.datasource.url=jdbc:mysql://localhost:3306/springbootdb?useUnicode=true&characterEncoding=utf8&useSSL=false
spring.datasource.username=root
spring.datasource.password=root
spring.datasource.driver-class-name=com.mysql.jdbc.Driver
spring.jpa.properties.hibernate.hbm2ddl.auto=update
spring.jpa.properties.hibernate.dialect=org.hibernate.dialect.MySQL5InnoDBDialect
spring.jpa.show-sql= true
spring.thymeleaf.cache=false
server.port=8888
3.新建用户实体并且与数据库表的列字段对应：
@Entity
@Table(name = "user")
public class User implements Serializable{
private static final long serialVersionUID = 1L;
@Id
@GeneratedValue
private Integer id;//ID主键
@Column(name = "user_name")
private String userName;//用户名
@Column(name = "pass_word")
private String passWord;//密码
@Column(name = "user_email")
private String email;//邮箱
@Column(name = "user_phone")
private String phone;//电话
@Column(name = "user_sex")
private String sex;//性别
@Column(name = "user_birthday")
private String birthday;//出生年月
@Column(name = "reg_time")
private String regTime;//注册时间
public User() {
super();
}
public User(Integer id, String userName, String passWord, String email,
String phone, String sex, String birthday, String regTime) {
super();
this.id = id;
this.userName = userName;
this.passWord = passWord;
this.email = email;
this.phone = phone;
this.sex = sex;
this.birthday = birthday;
this.regTime = regTime;
}
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;
}
public String getEmail() {
return email;
}
public void setEmail(String email) {
this.email = email;
}
public String getPhone() {
return phone;
}
public void setPhone(String phone) {
this.phone = phone;
}
public String getSex() {
return sex;
}
public void setSex(String sex) {
this.sex = sex;
}
public String getBirthday() {
return birthday;
}
public void setBirthday(String birthday) {
this.birthday = birthday;
}
public String getRegTime() {
return regTime;
}
public void setRegTime(String regTime) {
this.regTime = regTime;
}
}新建dao并且继承与JpaRepository：
这里写代码片public interface UserDao extends JpaRepository<User, Integer>{
User findById(Integer id);
User findByUserName(String userName);
Integer deleteById(Integer id);
User findByUserNameAndPassWord(String userName,String passWord);
}新建service服务类以及实现类：
这里写代码片public interface UserService {
public List getUserList();
public User findUserById(Integer id);
public void save(User user);
public void edit(User user);
public void delete(Integer id);
public User findByUserNameAndPassword(String userName,String passWord);
public Page findALL(Pageable pageable);
}
@Service
public class UserServiceImpl implements UserService{
@Autowired
private UserDao userDao;
@Autowired
/**
*
* Title: getUserList
* Description:获取用户列表
* @return
* @see com.ch.service.UserService#getUserList()
*/
public List getUserList() {
List userList = new ArrayList();
userList = userDao.findAll();
return userList;
}
public User findUserById(Integer id) {
User user = new User();
user = userDao.findById(id);
return user;
}
public void save(User user) {
user.setRegTime(DateUtil.getDateFormat(new Date()));
userDao.save(user);
}
public void edit(User user) {
user.setRegTime(userDao.findById(user.getId()).getRegTime());
userDao.save(user);
}
public void delete(Integer id) {
userDao.delete(id);
}
/**
*
* Title: findByUserNameAndPassword
* Description: 根据用户名密码查询用户
* @param userName
* @param passWord
* @return
* @see com.ch.service.UserService#findByUserNameAndPassword(java.lang.String, java.lang.String)
*/
public User findByUserNameAndPassword(String userName, String passWord) {
User user = new User();
user = userDao.findByUserNameAndPassWord(userName, passWord);
return user;
}
public Page findALL(Pageable pageable) {
return userDao.findAll(pageable);
}
4.controller的实现
这里写代码片@Controller
public class UserController {
@Resource
UserService userService;
private Log logger = LogFactory.getLog(UserController.class);
/**
*
* @Title: index
* @Description: 登录页面
* @param: @return
* @return: String
* @throws
*/
@RequestMapping("/")
public String index() {
return "user/index";
}
/**
*
* @Title: login
* @Description: 登录
* @param: @return
* @return: String
* @throws
*/
@RequestMapping("/login")
public String login(String userName,String passWord) {
User user = userService.findByUserNameAndPassword(userName, passWord);
if(user==null){
return "user/index";
}else{
return "redirect:/list";
}
}
/**
* 获取用户列表
*
*/
@RequestMapping("/list")
public String list(Model model) {
List users = userService.getUserList();
model.addAttribute("users", users);
return "user/list";
}
/**
* 分页查询所有用户列表
*
*/
@RequestMapping("/listPage")
public String listPage(Model model, Integer pageNum) {
int page = 0;
int size = 5;// 每页记录条数
page = 1;
// Sort sort = new Sort(Direction.DESC, "id");
// Pageable pageable = new PageRequest(page, size, sort);
Pageable pageable = new PageRequest(page, size);
Page userpage = userService.findALL(pageable);
model.addAttribute("pageable", pageable);
model.addAttribute("userpage", userpage);
return "user/listPage";
}
/**
* 跳转到用户注册页面
*
*/
@RequestMapping("/toAdd")
public String toAdd() {
return "user/userAdd";
}
/**
* 添加保存用户并返回列表页面
*
*/
@RequestMapping("/add")
public String add(User user) {
userService.save(user);
return "redirect:/listPage";
}
} 5.后台的代码都有了但是没有对应的页面代码，在resources下新建templates文件夹再在其下新建user文件夹，新建index.html,list.html,listPage等页面：
index.html:
这里写代码片

6.工程目录如下：
7.打开游览器访问：http://localhost:8888/ 进入登录页面：
输入用户名密码后登录：
