利用Groovy对参数进行处理

ParamUtils代码如下：

package com.ksource.utils;

import com.alibaba.fastjson.JSONArray;
import com.alibaba.fastjson.JSONObject;
import com.ksource.modules.serve.entity.ServeInfo;
import groovy.lang.Binding;
import groovy.lang.GroovyShell;
import groovy.lang.Script;
import org.codehaus.groovy.control.CompilationFailedException;
import java.util.*;
