jfinal maven项目jetty如何使用支持jsp - jfinal报错

我在IntelliJ 搭建jfinal + maven环境,依赖如下:


<dependencies>

    <dependency>

      <!--<scope>provided</scope>-->
    </dependency>

  </dependencies>

          <encoding>UTF-8</encoding>
        </configuration>
      </plugin>
    </plugins>
  </build>



启动类:



package com.ef.demo.common;
import com.jfinal.core.JFinal;
public class Stratup {

    public static void main(String[] args) {
        JFinal.start("src/main/webapp", 8080, "/", 5);
    }
}



Controller:



public class IndexController extends Controller {
    public void index(){
//        renderText("hello JFinal world!");//正常
        renderJsp("index.jsp");//报错: JSP support not configured
    }
}


以上配置启动正常但是访问jsp页面会报错:

JSP support not configured

我有2个问题:


1. 如何配置在开发环境(IntelliJ IDEA)maven+jetty+jsp(我已经尝试把官demo的jar的依赖都加进去了但还是不能renderJSP  )的依赖?

2. pom.xml 里面 jetty server的依赖的groupid用com.jfinal和用org.eclipse.jetty区别是什么?(如果把jfinal的jettey改成相同版本的eclipse的jetty则启动报错: Exception in thread "main" java.lang.NoClassDefFoundError: org/eclipse/jetty/webapp/WebAppContext )

@JFinal 或者谁能帮忙? 谢谢

  • Idea你就用你的jetty-maven-plugin插件启动就好了。

    pom里面jetty-server scope加上另外把JFinal和junit留下,其他的去掉。加上这个:

    <dependency>
    	<groupId>javax.servlet</groupId>
    	<artifactId>jstl</artifactId>
    	<version>1.2</version>
    </dependency>




    启动方法看图。

    下面给出 dependency:

        特别注意,其实最简单的方式,只需要第一个 jetty-jsp 即可,但 war 包打出来会包含很多 jetty 的东东,而通常你的生产环境用的是 tomcat,所以又需要去掉这些东东,所以上面做了一个拆分,并将 scope 全部声明为了 provided,打 war 包时不会包含这些东东。

    谢谢2位的仔细回答,我综合了一下,既能达到最简配置又能在开发(jetty)和生产(tomcat)切换,选择通过jetty-maven-plugin 启动项目而不是在java运行Main方法启动。(后者需要去掉provide scope才能正常启动,但这样又会造成package时候有多余jar)为方便后来者,这里贴出:

          <plugin>

            </configuration>
          </plugin>
        </plugins>
      </build>

    运行mvn jetty:run命令即可启动工程




    ######回复 @如梦技术 : 嗯嗯 intellij 右边有很方便的菜单 单击即可######如图,点一下那个红框框里面的就好,不用自己敲命令。######

    @如梦技术 , 问一个相关问题 intellij如何设置自动编译,像这样设置无效:http://www.360doc.com/content/14/1110/08/16002580_423959393.shtml

    否则每次改java需要手动点make麻烦

    我是intellij 14######

    这里再补充一下,新版本 jfinal 在用整合的 Jetty 启动时,需要使用下面的 depencency,前面给出的不再适用:

    <!-- jsp support by jetty -->
    <dependency>
    	<groupId>org.eclipse.jetty</groupId>
    	<artifactId>jetty-jsp</artifactId>
    	<version>8.1.8.v20121106</version>
    	<scope>provided</scope>
    </dependency>

    如果是 IDEA 下开发,要将 scope 改成 compile,在打 war 包时注意要再改回来成为 provided,独立部署用的容器大多都有 jsp 支持的 jar 包
