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;
  }
}
