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