遇到的问题:按照别人的blog搭thymeleaf页面就是html页面跳转不了,我那个郁闷呀!!!终于尝试了无数遍搞好了,报的错误是模板不存在。
ctrl层对比代码
易犯错误1
@RequestMapping(value ="/home_3", method = RequestMethod.GET)
@ResponseBody
public String homes(){
return "index3";
}//输入localhost:8081/home_3 只是返回了string字段为home_3 错误
@RequestMapping(value ="/homess")
public String homess(){
return "sys/index";
}//正确输出结果页面
}
易犯错误2
ctrl的标签是@Controller而不是@RestController,不然也会直接返回字段值
注意点 关于路径这一块可写可不写

本项目是打成war格式,外置tomcat启动。
项目结构:
pom.xml
<dependencies>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>
</dependency>
<!-- 测试 -->
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-test</artifactId>
<!-- 只在test测试里面运行 -->
<scope>test</scope>

<!--网页模板-->
<dependency>

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

注意添加的是
