java 中没有类似javascript中的eval()函数,无法直接将动态变化的字符串转换成java执行语句。此文档中提供两个jar包,和其api,使用非常简单。 Example of use: Expression exp = new Expression("(x + y)/2") Map<String, BigDecimal> variables = new HashMap<String, BigDecimal>() variables.put("x", new BigDecimal("4.32")) variables.put("y", new BigDecimal("342.1")) BigDecimal result = exp.eval(variables) System.out.println(result) -java does not like the javascript eval () function, can not directly change the dynamic execution of string into a java statement. This document provides two jar files, and its api, very simple to use. Example of use: Expression exp = new Expression (" (x+ y)/2" ) Map <String, BigDecimal> variables = new HashMap <String, BigDecimal> () Variables.put (" x" , new BigDecimal (" 4.32" )) variables.put (" y" , new BigDecimal (" 342.1" )) BigDecimal result = exp.eval (variables) System.out . println (result)
