第一步: 创建一个SpringBoot应用
第二步: 创建一个实体,用来存储数据,在src/main/java/com/example/first下创建包entity , 在entity下创建Person.java文件
package com.example.first.entity;
public class Person {
private String name;
private int age;
//seter , getter,toString方法
}
第三步: 创建resource, 在src/main/java/com/example/first下创建包resource, resource下创建PersonResource.java
package com.example.first.resource;
import com.example.first.entity.Person;
import org.springframework.stereotype.Controller;
import org.springframework.ui.ModelMap;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.RequestParam;
@Controller
@RequestMapping("/person")
public class PersonResource {
@RequestMapping(value = "/show",method = RequestMethod.GET) /**请求地址: localhost:8080/person/show?name=zhang&age=23 请求方式是get*/
private String show(@RequestParam("name")String name,@RequestParam("age")int age,ModelMap map){ /**@RequestParam("name")绑定请求地址中的name到参数name中 ModelMap map 存放返回内容*/
Person person = new Person();
person.setName(name);
person.setAge(age);
map.addAttribute("person",person);
return "index"; /**返回的是显示数据的html的文件名*/
}
}
第三步:创建index.html文件
<!DOCTYPE html>
<html xmlns:th="http://www.thymeleaf.org" lang="zh">
<head>
<meta charset="UTF-8"/>
<title>Title</title>
</head>
<body>
<span th:text="${person.name}"></span><hr/>
<span th:text="${person.age}"></span><hr/>
<span th:text="${person}"></span>
</body>
</html>
第四步:在application.properties中添加模板引擎
spring.thymeleaf.prefix=classpath:/templates/
spring.thymeleaf.suffix=.html
spring.thymeleaf.mode = HTML5
第五步: 在pom文件中添加依赖
<?xml version="1.0" encoding="UTF-8"?>
<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">

</properties>
<dependencies>
<dependency>

<artifactId>spring-boot-starter-test</artifactId>
<scope>test</scope>
</dependency>

<artifactId>spring-boot-starter-thymeleaf</artifactId>

<build>
<plugins>
<plugin>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-maven-plugin</artifactId>
</plugin>
</plugins>
</build>
</project>
第五步:启动前目录结构
第六步: 配置启动
第七步:启动SpringbootApplication
package com.example.first;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.web.bind.annotation.RestController;
@RestController
@SpringBootApplication
public class SpringbootApplication {
public static void main(String[] args) {
SpringApplication.run(SpringbootApplication.class, args);
}
}
第八步:在地址栏输入http://localhost:8080/person/show?name=zhang&age=23
第九步: 显示效果
