JAVA  druid 查询语句Json构造

Json原型：

{
    "fields": [
        {
            "dimension": "AA",
            "type": "or",
            "value": "11"
        },
        {
            "fields": [
                {
                    "dimension": "BB",
                    "type": "or",
                    "value": "22"
                },
                {
                    "dimension": "CC",
                    "type": "or",
                    "value": "33"
                }
            ],
            "type": "and"
        }
    ],
    "type": "and"
}

fields 类（外层类）：

package com.json;

import java.util.List;
import java.util.Map;

public class fields {

	private String type;
	private List<Object> fields;

	public String getType() {
		return type;
	}

	public void setType(String type) {
		this.type = type;
	}

	public List<Object> getFields() {
		return fields;
	}

	public void setFields(List<Object> fields) {
		this.fields = fields;
	}

}

package com.json3;

public class fields {

	private String type;
	private String dimension;
	private String value;

	public String getType() {
		return type;
	}

	public void setType(String type) {
		this.type = type;
	}

	public String getDimension() {
		return dimension;
	}

	public void setDimension(String dimension) {
		this.dimension = dimension;
	}

	public String getValue() {
		return value;
	}

	public void setValue(String value) {
		this.value = value;
	}

}

Main 方法构造输出：

package com.json;

import java.util.ArrayList;
import java.util.List;

import net.sf.json.JSONObject;

public class Main {

	
	public void setSturct()
	{
        
		fields fieldA = new fields();
		
		fields fieldB = new fields();
	
		
		
		
		List<Object> modelA30 = new ArrayList<>();
		
		com.json3.fields fieldObjectA30 = new com.json3.fields();
		fieldObjectA30.setType("or");
		fieldObjectA30.setDimension("AA");
		fieldObjectA30.setValue("11");
		modelA30.add(fieldObjectA30);
		
		//////////////////////////////////////////////////
		
		List<Object> modelA31 = new ArrayList<>();
		com.json3.fields fieldObjectA31 = new com.json3.fields();
		fieldObjectA31.setType("or");
		fieldObjectA31.setDimension("BB");
		fieldObjectA31.setValue("22");
		
		
		com.json3.fields fieldObjectA32 = new com.json3.fields();
		fieldObjectA32.setType("or");
		fieldObjectA32.setDimension("CC");
		fieldObjectA32.setValue("33");
		
		
		modelA31.add(fieldObjectA31);
		modelA31.add(fieldObjectA32);		
		
		
		fieldB.setType("and");
		fieldB.setFields(modelA31);
		

		modelA30.add(fieldB);
		
  ///////////////////////////////////////////////////////
		fieldA.setType("and");
		fieldA.setFields(modelA30);
		
		
		String result = JSONObject.fromObject(fieldA).toString();
		
		System.out.println(result);
		
	}

	public static void main(String[] args) {
		// TODO Auto-generated method stub

		new Main().setSturct();
	
	}

}

输出结果：

{
    "fields": [
        {
            "dimension": "AA",
            "type": "or",
            "value": "11"
        },
        {
            "fields": [
                {
                    "dimension": "BB",
                    "type": "or",
                    "value": "22"
                },
                {
                    "dimension": "CC",
                    "type": "or",
                    "value": "33"
                }
            ],
            "type": "and"
        }
    ],
    "type": "and"
}
