2.1.7. 在 Eclipse 中启动 jfinal 我的项目

右击 JFinalApplication.groovy 的 main 办法 –>Run As–>Java Application, 启动胜利, 如图

2.1.8. 查看编译后的 class 文件

2.2. 部署

部署和 jfinal 的原有的部署形式雷同

2.2.1. 生成可部署的产物

进入 groovy-ee-jfinal-4.9-hello 执行命令上面的命令

mvn clean pre-integration-test -DskipTests

执行胜利悔恨生成 groovy-ee-jfinal-4.9-hello-1.0-release.tar.gz
解压

2.2.2. 启动我的项目

在 windows 平台上执行 jfinal-start.bat 即可
最终调用的命令是

java -Xverify:none -cp config;lib\* com.litongjava.JFinalApplication

执行胜利

2.2.3. 测试

拜访一些接口测试
http://localhost
http://localhost/thisClassName
http://localhost/thisClassLoader
http://localhost/exception
测试胜利
