GroovyShell.evaluate介绍

[英]Evaluates some script against the current Binding and returns the result
[中]根据当前绑定计算某些脚本并返回结果

代码示例

代码示例来源：origin: org.codehaus.groovy/groovy

/**
 * A helper method to allow the dynamic evaluation of groovy expressions using this
 * scripts binding as the variable scope
 *
 * @param expression is the Groovy script expression to evaluate
 */
public Object evaluate(String expression) throws CompilationFailedException {
  GroovyShell shell = new GroovyShell(getClass().getClassLoader(), binding);
  return shell.evaluate(expression);
}

/**
 * Loads a set of given beans
 * @param resources The resources to load
 * @throws IOException
 */

    @Override
    public Object call(Object... args) {

  GroovyShell shell = classLoader != null ? new GroovyShell(classLoader,b) : new GroovyShell(b);
  for (Resource resource : resources) {
    shell.evaluate(new InputStreamReader(resource.getInputStream()));
  }
}
