注意事项:

a.静态资源访问

static下的js文件夹中的jquery.js访问方式为

b. 如果不用thymeleaf,想直接访问html文件,则直接放在static目录下就可以

http://localhost:8080/index2.html就可以访问放在static目录下的index2.html页面

1.导入依赖

<dependencies>

<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>
</dependency>

<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-test</artifactId>
<scope>test</scope>
</dependency>


<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-thymeleaf</artifactId>
</dependency>

<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-data-jpa</artifactId>
</dependency>

<dependency>
<groupId>mysql</groupId>
<artifactId>mysql-connector-java</artifactId>
</dependency>

</dependencies>

2.配置文件

spring.datasource.url=jdbc:mysql://127.0.0.1/test?useUnicode=true&characterEncoding=utf-8&serverTimezone=UTC&useSSL=true
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

3.controller

@Controller
public class UserController {

    @Autowired
    private UserService userService;

    @RequestMapping("/")
    public String index() {

        return "redirect:/list";
    }

    @RequestMapping("/list")
    public String list(Model model) {
        List<User> users=userService.getUserList();
        model.addAttribute("users", users);
        return "user/list";
    }

    @RequestMapping("/toAdd")
    public String toAdd() {
        return "user/userAdd";
    }

    @RequestMapping("/add")
    public String add(User user) {
        userService.save(user);
        return "redirect:/list";
    }

    @RequestMapping("/toEdit")
    public String toEdit(Model model,Long id) {
        User user=userService.findUserById(id);
        model.addAttribute("user", user);
        return "user/userEdit";
    }

    @RequestMapping("/edit")
    public String edit(User user) {
        userService.edit(user);
        return "redirect:/list";
    }


    @RequestMapping("/delete")
    public String delete(Long id) {
        userService.delete(id);
        return "redirect:/list";
    }
}
