JavaSpring表达式语言检查字符串列表中是否包含字符串

Question

我有以下SPEL测试代码：

public void test(){
    ExpressionParser parser = new SpelExpressionParser();

    String input = "ADITYA";
    List<String> coreTeam = Arrays.asList("ASHISH","ADITYA","SUMANT","SHASHIKANT","HATIM");

    System.out.println(coreTeam.toString());

    StandardEvaluationContext coreTeamContext = new StandardEvaluationContext(coreTeam);
    coreTeamContext.setVariable("CORE_TEAM",coreTeam);
    coreTeamContext.setVariable("CHEK_TEAM",input);

    Expression exp40 = parser.parseExpression("#CORE_TEAM.contains(#CHECK_TEAM)");
    Boolean s = exp40.getValue(coreTeamContext,Boolean.class);

}

其输出总是错误的

我错过了什么

Answer 1

这是打字错误，你输入了CHECK_TEAM iso“CHEK_TEAM”。下面的代码将为您提供真实信息。 ExpressionParser=new SpelExpressionParser（）

 String input = "ADITYA";
    List<String> coreTeam = Arrays.asList("ASHISH","ADITYA","SUMANT","SHASHIKANT","HATIM");

    System.out.println(coreTeam.toString());

    StandardEvaluationContext coreTeamContext = new StandardEvaluationContext(coreTeam);
    coreTeamContext.setVariable("CORE_TEAM",coreTeam);
    coreTeamContext.setVariable("CHEK_TEAM",input);

    Expression exp40 = parser.parseExpression("#CORE_TEAM.contains(#CHEK_TEAM)");
    Boolean s = exp40.getValue(coreTeamContext,Boolean.class);
