maven搭建springboot+thymeleaf

maven搭建springboot+thymeleaf

1.新建maven

自己创建包和文件夹。目录结构如下：

2.pom.xml

<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">
	<modelVersion>4.0.0</modelVersion>
	<groupId>com.ufo</groupId>
	<artifactId>test</artifactId>
	<version>0.0.1-SNAPSHOT</version>

	<dependencies>
		<dependency>
			<groupId>org.springframework.boot</groupId>
			<artifactId>spring-boot-starter-web</artifactId>
			<version>2.3.0.RELEASE</version>
		</dependency>
		<dependency>
			<groupId>org.springframework.boot</groupId>
			<artifactId>spring-boot-starter-thymeleaf</artifactId>
			<version>2.3.0.RELEASE</version>
		</dependency>
	</dependencies>


	<build>
		<plugins>

			<plugin>
				<groupId>org.springframework.boot</groupId>
				<artifactId>spring-boot-maven-plugin</artifactId>
			</plugin>
		</plugins>
	</build>

</project>

3.启动类app.java:

package com.ufo.test;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

@SpringBootApplication
public class app {

	public static void main(String[] args) {
        SpringApplication.run(app.class, args);
	}

}

4.testController.java

@Controller 
public class testController{
    
    @RequestMapping("/hello") 
    public String hello(HttpServletRequest request, @RequestParam(value = "name", defaultValue = "springboot-thymeleaf") String name) { 
        request.setAttribute("name", name); 
        return "hello"; 
    } 
}

5.配置文件application.yml:

spring.thymeleaf.prefix=classpath:/templates/ 
spring.thymeleaf.check-template-location=true 
spring.thymeleaf.suffix=.html 
spring.thymeleaf.encoding=UTF-8 
spring.thymeleaf.content-type=text/html 
spring.thymeleaf.mode=HTML5 
spring.thymeleaf.cache=false

6.测试界面hello.html

<!DOCTYPE html> 
<html lang="en" xmlns:th="http://www.thymeleaf.org"> 
<head> 
    <meta charset="UTF-8"/> 
    <title>springboot-thymeleaf测试</title> 
</head> 

<body> 
    <p th:text="'hello, ' + ${users} + '!'" /> 
</body>

</html>

启动启动类。成功。

7.thymeleaf列表

<!DOCTYPE html> 
<html lang="en" xmlns:th="http://www.thymeleaf.org"> 
<head> 
    <meta charset="UTF-8"/> 
    <title>springboot-thymeleaf测试</title> 
</head> 

<body> 
  <table border="1">
    <tr>
        <th>用户名</th>
        <th>邮箱</th>
        <th>状态变量：index</th>
        <th>状态变量：count</th>
        <th>状态变量：size</th>
        <th>状态变量：even</th>
        <th>状态变量：odd</th>
    </tr>
    <tr  th:each="user : ${users}" >
        <td th:text="${user.id}"></td>
        <td th:text="${user.name}"></td>
        <th th:text="${user.feature}"></th>
        <th th:text="${user.status}"></th>
        <th th:text="${user.dornum}"></th>
    
    </tr>
</table>
</body>

</html>

8.thymeleaf的ifelse

   <td th:switch = "${ user.status ==1  }" >
                <div th:case="true" th:text = "在校" ></div>
                <div th:case="false" th:text = "离校" ></div>
        </td>

或者用三目运算：

th:text="${emp.gender==0?'女':'男'}"

9.小心只返回hello，不返回界面

用controller不用RestController

10.只编译html

      spring.thymeleaf.cache=false
