本文介绍了SpringBoot 中使用JSP的方法示例，分享给大家，具体如下：

依赖：

  <parent>    <groupId>org.springframework.boot</groupId>    <artifactId>spring-boot-starter-parent</artifactId>    <version>1.5.1.RELEASE</version>    <relativePath/> <!-- lookup parent from repository -->  </parent>    <dependency>      <groupId>org.springframework.boot</groupId>      <artifactId>spring-boot-starter-web</artifactId>    </dependency>

示例代码：

  @RequestMapping(value = "/register", method = RequestMethod.GET)  @ResponseBody  public String register(){    return "user register";  }  /** @GetMapping 是Spring 4.3 的新特性 */  @GetMapping("getUser")  @ResponseBody  public String getUser(){    return "user get";  }  /** @PostMapping 也是Spring 4.3 的新特性 */  @PostMapping("createUser")  @ResponseBody  public String createUser(){    return "user create";  }  /**   * @RequestParam 接收提交的参数，参数默认是必填的   * @RequestParam(value = "password", required = false) required = false，可以不是必填的参数   *    */  @PostMapping("buildUser")  @ResponseBody  public String buildUser(@RequestParam("username") String username,                       @RequestParam(value = "password", required = false) String password){    return "提交的参数:username" + username + " password:" + password;  }

在SpringBoot中使用JSP

SpringBoot默认不支持JSP，需要在项目中添加相关的依赖

 <dependency>      <groupId>org.apache.tomcat.embed</groupId>      <artifactId>tomcat-embed-jasper</artifactId>    </dependency>    <dependency>      <groupId>org.eclipse.jdt.core.compiler</groupId>      <artifactId>ecj</artifactId>      <version>4.6.1</version>      <scope>provided</scope> </dependency>

配置文件增加配置项：

spring.mvc.view.prefix=/WEB-INF/views/spring.mvc.view.suffix=.jsp

@Controllerpublic class LoginController {  @PostMapping("login")  public String login(String username, String password){    if (username.equals(password)){      return "list";    }    return "login";  }  @GetMapping("form")  public String from(Model model){    model.addAttribute("username", "tomcat");    return "form";  }}
