本文详细阐述了在Java应用中遇到的由缺少ExpressionFactory类导致的InvocationTargetException错误的原因及解决方案。通过深入分析堆栈跟踪信息，定位到问题在于jsp-api.jar包中的ExpressionFactory类未实现newInstance方法，最终通过引入el-api.jar中的ExpressionFactory解决了问题。

今天遇到这个错误纠结了好久才发现问题所在。

结果尝试了N多边都是失败的，在网上搜了很多相关资料，发现使用这个最新版本的jar文章微乎其微。今早，跟踪源代码进去找原因，发现每次在ResourceBundleMessageInterpolator.java类中的interpolateExpression方法［341行InterpolationTerm expression = new InterpolationTerm( term, locale );］中抛出异常——javax.el.ExpressionFactory无法实例化，继续跟踪代码进去，发现InterpolationTerm类的构造方法很简单

public InterpolationTerm(String expression, Locale locale) {
        this.locale = locale;
        this.expression = expression;
        if ( expression.startsWith( EL_DESIGNATION_CHARACTER ) ) {
            this.type = InterpolationTermType.EL;
        }
        else {
            this.type = InterpolationTermType.PARAMETER;
        }
    }

开始认为这里不可能抛出异常，又尝试了很多边，发现问题就出现InterpolationTerm实例化过程中，既然构造方法没问题，那么肯定在其他的static块或者方法中存在问题，继续找相关代码。编译器已经提示存在问题了

static {
        expressionFactory = ExpressionFactory.newInstance();
    }

问题在这里，ExpressionFactory工厂类里未定义newInstance方法。

至此，问题原因找到了，是由于ExpressionFactory工厂类出错了。

既然找到了错误，那么这个类是在哪个jar包里呢？

结果发现这个类是在jsp-api.jar包里,那么也就是说hibernate-validator.5.1.0.Final不能使用jsp-api.jar的ExpressionFacotry类,那使用哪个呢？

找到了原因，距离问题解决就不远了，继续在网上找答案……

ExpressionFactory这个类是属于el-api.jar，解决办法就是引入下面的jar文件（会把el-api.jar导入）

<dependency>
    <groupId>org.glassfish.web</groupId>
    <artifactId>el-impl</artifactId>
    <version>2.2</version>
</dependency>

至此问题解决了。
