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）引入js，需要使用如下格式
<html lang="en" xmlns:th="http://www.thymeleaf.org">
<script type="text/javascript" th:src="@{/js/jquery/jquery.min.js}"></script>
<script type="text/javascript" th:src="@{/js/jquery/jquery.easyui.min.1-7-5.js}"></script>
<script type="text/javascript" th:src="@{/js/jquery/easyui-lang-zh_CN.js}"></script>
<script type="text/javascript" th:src="@{/js/index.js}"></script>
<body>
<h2>Hello World!</h2>
</body>
</html>
（4）controller代码如下
package springboot.controller;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
@Controller
public class HtmlController {
@RequestMapping("/show")
public String show() {
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
三、加载css、js文件
放到static下
