Java MVC + ORM框架 Nano Framework之环境搭建

1、创建Maven Webapp

2、pom.xml中添加依赖(使用前先安装，见前一篇文章，目前未发布至公共仓库)

<dependency>
	<groupId>org.nanoframework</groupId>
	<artifactId>nano-webmvc</artifactId>
	<version>1.2.0-RC1</version>
</dependency>

3、web.xml中添加DispatcherServlet和HttpRequestFilter

<filter>
	<filter-name>httpRequestFilter</filter-name>
	<filter-class>org.nanoframework.web.server.filter.HttpRequestFilter</filter-class>
</filter>

<filter-mapping>
	<filter-name>httpRequestFilter</filter-name>
	<url-pattern>/*</url-pattern>
</filter-mapping>

<servlet>
	<servlet-name>Dispatcher-Servlet</servlet-name>
	<servlet-class>org.nanoframework.web.server.servlet.DispatcherServlet</servlet-class>
	<init-param>
		<param-name>context</param-name>
		<param-value>/context.properties</param-value>
	</init-param>
	<load-on-startup>1</load-on-startup>
</servlet>

<servlet-mapping>
	<servlet-name>Dispatcher-Servlet</servlet-name>
	<url-pattern>/dispatcher/*</url-pattern>
</servlet-mapping>

4、在src/main/resources下添加属性文件context.properties(servlet中的context配置)，并添加以下内容

context.root=/first-webapp
context.component-scan.base-package=org.nanoframework.examples.first.webapp.component

5、修改工程的Web Project Settings，是其与context.properties属性文件中的context.root保持一致

6、添加第一个组件服务
6.1、在包org.nanoframework.examples.first.webapp.component下建立HelloWorldComponent接口

import org.nanoframework.core.component.stereotype.Component;
import org.nanoframework.core.component.stereotype.bind.RequestMapping;
import org.nanoframework.examples.first.webapp.component.impl.HelloWorldComponentImpl;

@Component
@ImplementedBy(HelloWorldComponentImpl.class)
@RequestMapping("/first")
public interface HelloWorldComponent {
	@RequestMapping("/hello")
	Object hello();
}

6.2、在包org.nanoframework.examples.first.webapp.component.impl下建立HelloWorldComponentImpl实现类

public class HelloWorldComponentImpl implements HelloWorldComponent {
	@Override
	public Object hello() {
		return "Hello Nano Framework!";
	}
}

7、添加web容器，运行服务，并访问http://ip:port/first-webapp/first/hello

8、至此最基础的服务已经搭建完成
