第一个SpringBoot

新公司不用SpringMVC，而自己也觉得SpringMVC配置起来确实繁琐，今天记录下配置SpringBoot的过程

工具是IDEA

1.配置pom.xml

<?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">
    <modelVersion>4.0.0</modelVersion>
    <parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>2.1.3.RELEASE</version>
        <relativePath/> <!-- lookup parent from repository -->
    </parent>
    <groupId>com.example</groupId>
    <artifactId>demo</artifactId>
    <version>0.0.1-SNAPSHOT</version>
    <name>demo</name>
    <description>Demo project for Spring Boot</description>

    <properties>
        <java.version>1.8</java.version>
    </properties>

    <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>
    </dependencies>

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

</project>

2. 配置application.properties

server.port=8081
server.servlet.context-path=/boy
spring.mvc.view.prefix=/pages/
spring.mvc.view.suffix=.html
cupSize:C
name:王XX
age=20

server.servlet.context-path=/boy配置项目访问路径

 spring.mvc.view.prefix=/pages/                     spring.mvc.view.suffix=.html这两个是配置后端访问html页面的；

3.Controller

TestController：

@Controller
@RequestMapping
public class TestController {
    @RequestMapping(value = "/page")
    public String home() {
        return "index";
    }
}

HelloController：

@RestController
public class HelloController {

    @Value("${cupSize}")
    private String cupSize;

    @Value("${name}")
    private String name;

    @Value("${age}")
    private String age;

    @RequestMapping(value = "/hello",method = RequestMethod.GET)
    public String say(){
        return "亲爱的"+name+"同学,"+"你的年纪只有"+age+",但你的成绩却是"+cupSize;
    }

    @RequestMapping("/html")
    public String helloHtml(){
        return "/index";
    }
}

TestController和HelloController用处不同，最后我访问就知道了
