Spring Boot整合JSP

環境：Eclipse Photon Release (4.8.0)
	  Maven3.3.3
	  jdk1.8
	  Spring Boot 1.5.15.RELEASE
		  

1. 搭建專案      新建一個maven專案，打包型別為jar，在專案的結構的src\main中新建目錄webapp\WEB-INF，用來存放JSP檔案。其中jsp檔案存放位置為WEB-INF\jsp\目錄下。 2. pom檔案匯入依賴

	<parent>
		<groupId>org.springframework.boot</groupId>
		<artifactId>spring-boot-starter-parent</artifactId>
		<version>1.5.15.RELEASE</version>
	</parent>

	<properties>
		<project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
		<project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding>
		<java.version>1.8</java.version>
	</properties>

	<dependencies>
		<!-- spring boot的web啟動器 -->
		<dependency>
			<groupId>org.springframework.boot</groupId>
			<artifactId>spring-boot-starter-web</artifactId>
		</dependency>
		<!-- jstl標籤依賴 -->
		<dependency>
		    <groupId>javax.servlet</groupId>
   			<artifactId>jstl</artifactId>
		</dependency>
		<!-- jsp引擎 -->
		<dependency>
			<groupId>org.apache.tomcat.embed</groupId>
    		<artifactId>tomcat-embed-jasper</artifactId>
    		<scope>provided</scope>
		</dependency>
	</dependencies>

 

3. 編寫Controller和實體POJO

	/**
	 * 實體類User
	 */
	public class User implements Serializable {
	private static final long serialVersionUID = 5549535290224286007L;
	private Integer userid;
	private String username;
	private Integer userage;
	public User() {
		super();
	}
	public User(Integer userid, String username, Integer userage) {
		super();
		this.userid = userid;
		this.username = username;
		this.userage = userage;
	}
	public Integer getUserid() {
		return userid;
	}
	public void setUserid(Integer userid) {
		this.userid = userid;
	}
	public String getUsername() {
		return username;
	}
	public void setUsername(String username) {
		this.username = username;
	}
	public Integer getUserage() {
		return userage;
	}
	public void setUserage(Integer userage) {
		this.userage = userage;
	}
}

	/**
	 * 控制器
	 */
	@Controller
	public class UserController {
	@RequestMapping("/showUser")
	public String showUser(Model model) {
		List<User> list = new ArrayList<>();
		list.add(new User(1, "xiaoming", 19));
		list.add(new User(2, "xiaohong", 18));
		list.add(new User(3, "xiaoli", 17));
		
		model.addAttribute("list", list);
		
		return "userList";
	}
}
 

4. 新增SpringBoot配置檔案application.properties 在配置檔案中加入SpringMVC檢視解析器的字首和字尾路徑

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

5. 編寫啟動類，並啟動測試

@SpringBootApplication
public class App {

	public static void main(String[] args) {
		SpringApplication.run(App.class, args);
	}
}

6. 測試結果展示
