1、新建一個maven web project;

2、在pom.xml文件中添加相應的依賴包；

3、新建一個HelloController請求控制類；

4、編寫index.jsp頁面；

5、編寫啟動類App.java

6、啟動應用程序進行代碼測試

App.java

package boot2.muyang.app;import org.apache.log4j.Logger; import org.springframework.boot.SpringApplication; import org.springframework.boot.autoconfigure.SpringBootApplication; import org.springframework.boot.autoconfigure.web.HttpMessageConverters; import org.springframework.context.annotation.Bean; import org.springframework.http.converter.HttpMessageConverter;import com.alibaba.fastjson.serializer.SerializerFeature; import com.alibaba.fastjson.support.config.FastJsonConfig; import com.alibaba.fastjson.support.spring.FastJsonHttpMessageConverter;@SpringBootApplication public class App {private static Logger logger = Logger.getLogger(App.class);@Beanpublic HttpMessageConverters fastJsonHttpMessageConverters(){FastJsonHttpMessageConverter fastConverter = new FastJsonHttpMessageConverter();FastJsonConfig fastJsonConfig = new FastJsonConfig();fastJsonConfig.setSerializerFeatures(SerializerFeature.PrettyFormat);fastConverter.setFastJsonConfig(fastJsonConfig);HttpMessageConverter<?> converter = fastConverter;return new HttpMessageConverters(converter);}public static void main(String[] args){logger.info("----: run start");SpringApplication.run(App.class, args);logger.info("----: runing");}}

application.properties不能有空格

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

　　

HelloController.java

package boot2.muyang.app.controller;import java.util.Map;import org.springframework.stereotype.Controller; import org.springframework.web.bind.annotation.RequestMapping;@Controller @RequestMapping("/hello") public class HelloController {@RequestMapping("/index")public String index(Map<String,Object> map){map.put("name", "Andy");return "index";} }
