springboot教程3——模板引擎jsp

 

1 将使用JSP作为模板引擎的Maven依赖导入进来

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


	javax.servlet
	jstl

2 在application.properties添加如下内容：

//文件前缀
spring.mvc.view.prefix=/WEB-INF/jsp/
//文件后缀
spring.mvc.view.suffix=.jsp

3 代码演示

SpringBootDemo81Application （启动）

package com.roncoo.education;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

@SpringBootApplication
public class SpringBootDemo81Application {

	public static void main(String[] args) {
		SpringApplication.run(SpringBootDemo81Application.class, args);
	}
}

package com.roncoo.education.controller;

import org.springframework.stereotype.Controller;
import org.springframework.ui.ModelMap;
import org.springframework.web.bind.annotation.RequestMapping;

/**
 * @author wujing
 */
@Controller
@RequestMapping(value = "/web")
public class WebController {

	@RequestMapping(value = "index")
	public String index(ModelMap map) {
		map.put("title", "thymeleaf hello word");
		return "index";
	}

}

    ServletInitializer.java

package com.roncoo.education;

import org.springframework.boot.builder.SpringApplicationBuilder;
import org.springframework.boot.web.support.SpringBootServletInitializer;

/**
 * 在Servlet容器中部署WAR的时候，不能依赖于Application的main函数而是要以类似于web.xml文件配置的方式来启动Spring应用上下文

 * 所以此时需要声明这样一个类或者将应用的主类改为继承SpringBootServletInitializer也可以
 * 
 * @author wujing
 */
public class ServletInitializer extends SpringBootServletInitializer {

	@Override
	protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
		return application.sources(SpringBootDemo81Application.class);
	}

}
