• IDEA搭建ssm项目

    此前，我一直在用eclipse编辑器做java项目，现在初次使用IDEA编辑器，在这里，我记录了使用IDEA环境下搭建ssm项目的过程。

    创建Maven项目，如下

    右击TEST4项目，在弹出的菜单中选择Add Framework Support

    在弹出的菜单中选择Web Application

    此时在Test4项目中新增了web相关元素，具体结构如下：

    接下来，我们在项目中添加tomcat服务器，在IDEA的上方点击Edit Configurations，进入tomcat设置窗口。如下

    在窗口中点击+号，并选择Local，

    在设置窗口中，可配置tomcat服务器

    在TEST4目录下，创建了t1.jsp的文件，然后启动tomcat服务器，即可通过http://localhost:8080/Test4_war_exploded/t1.jsp访问该页面。我的项目名为Test4，我的url路径中却包含Test4_war_exploded。

    右击Test4，在弹出的菜单中选择Open Module Settings，设置如下所示

    同时在服务器配置中，重新添加artifact

    在浏览器输入http://localhost:8080/Test4/t1.jsp，即可打开。

    接下来，引入ssm相关库，我在pom.xml文件中加入以下内容，点击reload后即自动联网下载完毕相关jar包。

    然后再进行Put into Output Root操作，如下：

    servlet-context.xml如下：

    WebConfig.java如下：

    7. import org.springframework.web.servlet.ViewResolver;
    8. import org.springframework.web.servlet.config.annotation.EnableWebMvc;
    9. import org.springframework.web.servlet.config.annotation.ResourceHandlerRegistry;
    10. import org.springframework.web.servlet.config.annotation.WebMvcConfigurerAdapter;
    11. import org.springframework.web.servlet.view.InternalResourceViewResolver;
    12.  
    13.  
    14. @Configuration
    15. @EnableWebMvc
    16. @EnableTransactionManagement
    17. @ComponentScan({"com.test4.web"})
    18. public class WebConfig extends WebMvcConfigurerAdapter{
    19. 	@Bean
    20. 	public ViewResolver viewResolver() {
    21. 		System.out.println("WebConfig viewResolver------------");
    22. 		InternalResourceViewResolver resolver=new InternalResourceViewResolver();
    23. 		resolver.setPrefix("/WEB-INF/");
    24. 	    resolver.setSuffix(".jsp");
    25. 	    return resolver;
    26. 	}
    27. }

    那么，如何在不联网的时候引入jar包呢，需要进行如下操作。在library中点+按钮选择本地jar所在的目录。如下图

    同时在WEN-INF中新建lib目录，复制粘贴jar到该ib目录，如下图，即完成了引入。
