标签:bean   1.2   iba   converter   没有   autoconf   jsp标签   def   热部署   


1、新建一个maven web project;

2、在pom.xml文件中添加相应的依赖包;

3、新建一个HelloController请求控制类;

4、编写index.jsp页面;

5、编写启动类App.java

6、启动应用程序进行代码测试

 

pom.xml配置

 
 <!-- Inherit defaults from Spring Boot -->
    <parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>

    <plugins>
  	
  	<!-- spring boot devtools的plugin -->
  	<plugin>
  		<groupId>org.springframework.boot</groupId>
  		<artifactId>spring-boot-maven-plugin</artifactId>
  		<configuration>
  			<!--fork :  如果没有该项配置,呢个devtools不会起作用,即应用不会restart -->
  			<fork>true</fork>
  		</configuration>
  	</plugin>  	
  	
  	</plugins>
  	
  	</build>

  

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);

	
	
	@Bean
	public 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";
	}
}
