添加JSP配置

1.pom.xml添加jsp解析引擎

<dependency>
<groupId>org.apache.tomcat.embed</groupId>
<artifactId>tomcat-embed-jasper</artifactId>
<scope>provided</scope>
</dependency>
<dependency>
<groupId>javax.servlet</groupId>
<artifactId>jstl</artifactId>
<scope>provided</scope>
</dependency>

2.在项目com.xxxx下创建文件夹config，在com.xxx.config下添加spring-boot配置JspConfig.java

public class JspConfig extends WebMvcConfigurerAdapter{
@Bean
public InternalResourceViewResolver internalResourceViewResolver () {
InternalResourceViewResolver viewResolver = new  InternalResourceViewResolver();
viewResolver.setPrefix("/WEB-INF/views/");
viewResolver.setSuffix(".jsp");
return viewResolver;
}
@Override
public void configureDefaultServletHandling(DefaultServletHandlerConfigurer configurer) {
configurer.enable();
}
}

3.创建/src/main/webapp/WEB-INF/views

目录结构

src --- main --- java
|    | --- basic
|    | --- config
|    | --- controller       |
|    | --- service
|    | --- persistent
|
| --- resources
|
| --- webapp --- WEB-INF - views

<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>
<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<html>
<h1>Login Page</h1>
<!--表单提交目标链接和方法post-->
<form action="/account/valid" method="post">
<input type="text" name="name" placeholder="用户名">
<input type="password" name="password" placeholder="密码">
<input type="submit" value="登录">
</form>
</html>

AccountController.java

@Controller
@RequestMapping("/account") //RequestMapping可对类和方法做映射
public class AccountController {
@Autowired //自动封装注解，省去set、get方法和实例化声明
AccountService accountService;
@RequestMapping(value="/login")
public String Login() {
return "login"; //没有用ResponseBody，返回string，跳转的是jsp页面："login" + ".jsp"后缀
}
@RequestMapping("/valid")
@ResponseBody
public String Valid(HttpServletRequest request) {
Account account = new Account();
account.setName(request.getParameter("name"));
account.setPassword(request.getParameter("password"));
if(accountService.valid(account)) {
return "Login Success!";
}
else {
return "Login Failed!";
}
}
}

AccountService.java

@Service
public class AccountService {
public boolean valid (Account account) {
if("admin".equals(account.getName()) && "123456".equals(account.getPassword())) {
return true;
}
return false;
}
}
