使用myeclipse构建maven管理的springmvc项目

1.创建一个maven webapp项目。

2.完善项目源文件夹

src/main/java,src/main/resources,src/test/java,src/test/resources.

3.更改项目字符集，右击项目，properties-resources.

4.更改web工程版本，进入myeclipse-project facets ,将dynatic web变为3.0.

5.修改发布目录，将Deployment Assembly里面的test删掉。将maven dependency 配置到 “WEB-INF/lib”,src/main/webapp配置到“/”,将src/main/java和src/main/resources配置到“WEB-INF/classes”

6.在pom中添加servlet，junit，spring-web，spring-webmvc依赖，

7.在src/main/java下编写配置类（例如在kai.config包中）

package kai.web.config;

import org.springframework.web.servlet.support.AbstractAnnotationConfigDispatcherServletInitializer;

public class SpitWebAppInitializer extends

AbstractAnnotationConfigDispatcherServletInitializer {

@Override
protected Class<?>[] getRootConfigClasses() {
// TODO Auto-generated method stub
return new Class<?>[]{RootConfig.class};
}

@Override
protected Class<?>[] getServletConfigClasses() {
// TODO Auto-generated method stub
return new Class<?>[]{WebConfig.class};
}

@Override
protected String[] getServletMappings() {
// TODO Auto-generated method stub
return new String[]{"/"};
}

}

8.在kai.web.config包中编写俩个应用上下文RootConfig和WebConfig。

package kai.web.config;

import org.springframework.context.annotation.ComponentScan;

import org.springframework.context.annotation.ComponentScan.Filter;

import org.springframework.context.annotation.Configuration;

import org.springframework.context.annotation.FilterType;

import org.springframework.web.servlet.config.annotation.EnableWebMvc;

@Configuration

@ComponentScan(basePackages={“kai.web.service”},excludeFilters={@Filter(type=FilterType.ANNOTATION,value=EnableWebMvc.class)})

public class RootConfig {

}package kai.web.config;

import org.springframework.context.annotation.Bean;

import org.springframework.context.annotation.ComponentScan;

import org.springframework.context.annotation.Configuration;

import org.springframework.web.servlet.ViewResolver;

import org.springframework.web.servlet.config.annotation.DefaultServletHandlerConfigurer;

import org.springframework.web.servlet.config.annotation.EnableWebMvc;

import org.springframework.web.servlet.config.annotation.WebMvcConfigurerAdapter;

import org.springframework.web.servlet.view.InternalResourceViewResolver;

@Configuration

@EnableWebMvc

@ComponentScan(“kai.web.controller”)

public class WebConfig extends WebMvcConfigurerAdapter{

@Bean

public ViewResolver viewResolver(){

InternalResourceViewResolver resolver=new InternalResourceViewResolver();

resolver.setPrefix(“/WEB-INF/views/”);

resolver.setSuffix(“.jsp”);

resolver.setExposeContextBeansAsAttributes(true);

return resolver;

}

@Override

public void configureDefaultServletHandling(

DefaultServletHandlerConfigurer configurer) {

// TODO Auto-generated method stub

configurer.enable();

}

}

9.然后就可以编写控制器来实现功能了。

在kai.web.controller包下创建一个新的控制器来试试。

package kai.web.controller;

import org.springframework.stereotype.Controller;

import org.springframework.web.bind.annotation.RequestMapping;

import org.springframework.web.bind.annotation.RequestMethod;

@Controller

public class HomeController {

@RequestMapping(value=”/”,method=RequestMethod.GET)

public String home() {

// TODO Auto-generated method stub

return “home”;

}

}

10.最后在WEB-INF/views/下编写一个home.jsp就行了。

访问localhost:8080/springdemo页面显示：
