springboot返回html和jsp

一、返回html

（1）添加maven依赖

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-thymeleaf</artifactId>
</dependency>
（2）thymeleaf模板默认寻找resources下，templates文件夹放html页面，static文件夹放css及js

（3）controller代码如下

@Controller
@RequestMapping("money")
public class MoneyController {
    @GetMapping("/description")
    public String getDescription(){
        return "aaa";
    }
}

二、返回jsp

（1）添加jsp的maven依赖

<dependency>
    <groupId>org.apache.tomcat.embed</groupId>
    <artifactId>tomcat-embed-jasper</artifactId>
<scope>provided</scope>
</dependency>
<dependency>
    <groupId>javax.servlet</groupId>
<artifactId>jstl</artifactId>
</dependency>
注：返回jsp需要把spring-boot-starter-thymeleaf注释掉

（2）在controller里添加寻找jsp页面的视图解析器

@Bean
public InternalResourceViewResolver viewResolver() {
      InternalResourceViewResolver viewResolver = new InternalResourceViewResolver();
　　viewResolver.setPrefix("/WEB-INF/");
　　viewResolver.setSuffix(".jsp");
　　return viewResolver;
}
（3）结构图如下

（4）controller代码如下

package springboot.controller;

import org.springframework.context.annotation.Bean;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.servlet.view.InternalResourceViewResolver;

@Controller
public class JspController {
@RequestMapping("/test")
public String index() {
return "home";
}
@Bean
public InternalResourceViewResolver viewResolver() {
InternalResourceViewResolver viewResolver = new InternalResourceViewResolver();
viewResolver.setPrefix("/WEB-INF/");
viewResolver.setSuffix(".jsp");
return viewResolver;
}
}
注：返回html和jsp时使用@Controller注解
