Mybatis 判断表达式除坑

Mybatis 判断表达式经常有各种坑，比如数值的判断，空值的判断坑等，可以通过如下代码测试一下是否符合预期

import org.apache.ibatis.ognl.Ognl;
import org.apache.ibatis.ognl.OgnlException;
import org.junit.Test;

import java.util.HashMap;
import java.util.Map;

public class Ongl {
    @Test
    public void testOngl() throws OgnlException {
        Map<String,Integer> reqMap = new HashMap<>();
        reqMap.put("status", -1);
        Map<String,Map<String,Integer>> param = new HashMap<>();
        param.put("request", reqMap);
        System.out.println(Ognl.getValue(Ognl.parseExpression("request.status != null and request.status != -1"), param));
    }
}
