SpringBoot创建JSP登录页面功能实例代码

添加JSP配置

1.pom.xml添加jsp解析引擎

  org.apache.tomcat.embed
  tomcat-embed-jasper
  provided


  javax.servlet
  jstl
  provided

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" %>

  Login Page
    
  

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;
  }
}
