这些问题，单个看每个问题都不算复杂或高深，但是都是在实际项目开发中出现并一度造成困扰的，而且带有一定的普适性，具体表现为不知道这些问题的同学很容易在日常开发中中招。因此我们开了一个专题，叫做编码最佳实践，似乎名字起的有点大......

javax.el.ExpressionFactory.newInstance()Ljavax/el/ExpressionFactory;

检查了一下，发现javax.el.ExpressionFactory.newInstance()这个方法是EL2.2版本之后才有的方法，而在EL2.1之中是没有这个方法的，问题很明显：org.apache.jasper中试图调用2.2版本的EL，当时提供的EL的版本是2.1版本，所以解决的方式无非就是两个，要不降低org.apache.jasper的版本，要不提升el的版本。考虑到现在使用的jetty已经是最新的版本8.1.2.v20120308，因此提升EL的版本为2.2更为合适。  阅读全文

    使用maven填写依赖的时候，常会遇到需要查一下groupId/artifactId和version，有时候还要看看有没有新的版本更新。 

    原来一直用http://mvnrepository.com/ 这个网站来搜索，最近发现maven官网也提供了类似的功能，http://search.maven.org/。 

    简单试用了一下search.maven.org，功能基本和mvnrepository.com相同，而且界面更简洁友好。推荐使用。

但是在某些情况下，我们可能无法预知返回值，比如我们需要根据输入的参数值来决定返回什么，而这个参数可能无法在record阶段获得。因此在mock方法中我们无法在record阶段就决定应该返回什么。

对于这种场景，easymock提供了IAnswer接口和andAnswer()方法来提供运行时决定返回值或者异常的机制。  阅读全文
