为什么我不能运行Spring程序? [英] Why i am not able to run Spring program?

问题描述

当我尝试在Eclipse中运行spring程序时，出现以下错误.

While i am trying to run spring program in eclipse i get following error.

Exception in thread "main" java.lang.Error: Unresolved compilation problems: 
    BeanFactory cannot be resolved to a type
    XmlBeanFactory cannot be resolved to a type
    FileSystemResource cannot be resolved to a type
    triangle cannot be resolved

    at Org.koushik.javabrains.DrawingApp.main(DrawingApp.java:8)

我试图解决此错误.我也下载了spring.jar文件并将其放在类路径中.但是，仍然出现错误.我还希望整个spring.jar其中应包括所有spring.jar文件.

I tried to resolve this error. I also download spring.jar file and put it in the classpath.But, still i am getting error.I also want whole spring.jar which should include all spring.jar file.

请帮助我，谢谢.

推荐答案

要使用诸如 Maven 之类的工具来管理依赖项， Gradle 或

To manage your dependencies use tools like Maven, Gradle or Ant + Ivy. Those will make your life a whole lot easier, the dependencies will be managed and you will get also all transitive dependencies (the dependencies the framework you use depends on). This will save you a lot of searching around the internet.

使用这两种工具之一，您都可以创建一个构建文件(ant和maven使用XML，Gralde为此使用Groovy)并表达您的依赖关系.

With either of these tools you create a build file (ant and maven use XML, Gralde uses Groovy for that) and express your dependencies.

例如，用于gradle的此构建文件 build.gradle 将创建一个jar并使用所有依赖项.

For example this build file for gradle, build.gradle will create a jar and use all the dependencies.

apply plugin: 'java'

repositories {
    mavenCentral()
}

dependencies {
    compile group: 'org.springframework', name: 'spring-context', version: '3.2.5.RELEASE'        
    compile group: 'org.springframework', name: 'spring-context-support', version: '3.2.5.RELEASE'        
    testCompile group: 'junit', name: 'junit', version: '4.+'
}

此 gradle.build 将添加所需的spring jar和其所需的依赖项.

This gradle.build will add the needed spring jars and the dependencies it needs for that.
