本文整理了Java中org.springframework.expression.AccessException类的一些代码示例，展示了AccessException类的具体用法。这些代码示例主要来源于Github/Stackoverflow/Maven等平台，是从一些精选项目中提取出来的代码，具有较强的参考意义，能在一定程度帮忙到你。AccessException类的具体详情如下：
包路径：org.springframework.expression.AccessException
类名称：AccessException

AccessException介绍

[英]An AccessException is thrown by an accessor if it has an unexpected problem.
[中]如果访问器出现意外问题，则会引发访问异常。

代码示例

代码示例来源：origin: spring-projects/spring-framework

@Override
public Object resolve(EvaluationContext context, String beanName) throws AccessException {
  try {
    return this.beanFactory.getBean(beanName);
  }
  catch (BeansException ex) {
    throw new AccessException("Could not resolve bean reference against BeanFactory", ex);
  }
}

/**
 * Decode the AccessException, throwing a lightweight evaluation exception or,
 * if the cause was a RuntimeException, throw the RuntimeException directly.
 */

  if (ex.getCause() instanceof InvocationTargetException) {
    Throwable rootCause = ex.getCause().getCause();
    if (rootCause instanceof RuntimeException) {

    }
    throw new ExpressionInvocationTargetException(getStartPosition(),
        "A problem occurred when trying to execute method '" + this.name +
        "' on object of type [" + value.getClass().getName() + "]", rootCause);
