java static 方法使用笔记

有入参的static方法，可以正常使用

static的作用是申明：这是类的静态方法，什么时候都可以调用，可以传入入参，也可以不传。

上代码：

1.带静态方法的类：

public class MakeParameters {

    public static InsuranceSearchRQ makeBaseRqParms(InsuranceSearchRQ rq){
        ChannelInfo channel = new ChannelInfo();
        channel.setFirstChannelNo(BaseConst.FIRST_CHANNEL_NO);
        channel.setWebSite(BaseConst.WEB_SITE);
        
        rq.setChannelInfo(channel);
        rq.setLanguage(BaseConst.LANGUAG);
        rq.setTimeStamp(BaseConst.TIMESTAMP);
        rq.setTransactionId(BaseConst.TRANSACTION_ID);
        rq.setVersion(BaseConst.VERSION);
            
        return rq;
    }

}

2.测试类：

　　

package com.doit.zz;

import org.junit.Test;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;

import com.basemake.zz.MakeParameters;
import com.travelsky.logic.insurance.dto.InsuranceSearchRQ;
import com.travelsky.logic.insurance.dto.InsuranceSearchRS;
import com.travelsky.logic.insurance.dto.MaintainQueryParam;
import com.travelsky.logic.shopping.service.IInsuranceSearchService;
import com.utils.zz.JsonMapper;

public class InsureTest {
    ApplicationContext ctx=new ClassPathXmlApplicationContext("helloservice.xml");
    
    @Test
    public void testInsure() throws Exception{        
        InsuranceSearchRQ rq=new InsuranceSearchRQ();
        MaintainQueryParam maintainQueryParam=new MaintainQueryParam();
        maintainQueryParam.setProductCode("7000000");
        rq.setMaintainQueryParam(maintainQueryParam);
        MakeParameters.makeBaseRqParms(rq);
        System.out.println(JsonMapper.toNonNullJson(rq));//1
                
        maintainQueryParam.setProductCode("12345");
        InsuranceSearchRQ rq2=new InsuranceSearchRQ();
        rq2.setMaintainQueryParam(maintainQueryParam);        
        MakeParameters.makeBaseRqParms(rq2);
        System.out.println(JsonMapper.toNonNullJson(rq2));//2
        
        InsuranceSearchRS rs=new InsuranceSearchRS();
        IInsuranceSearchService insService=(IInsuranceSearchService)ctx.getBean("iInsuranceSearchService");
        rs=insService.getInsuranceSearchRS(rq);
        
        String rsJson = JsonMapper.toNonNullJson(rs);
        System.out.println(rsJson);            
    }
    
    

}

3.结果

{"channelInfo":{"firstChannelNo":"71","webSite":"zh_CN"},"timeStamp":"20150108161025","version":"0.01","transactionId":"20150108161025","language":"zh","insTravelerInfos":[],"maintainQueryParam":{"productCode":"7000000"}}
{"channelInfo":{"firstChannelNo":"71","webSite":"zh_CN"},"timeStamp":"20150108161025","version":"0.01","transactionId":"20150108161025","language":"zh","insTravelerInfos":[],"maintainQueryParam":{"productCode":"12345"}}

在1处和2出分别打印调用静态方法结果

可以看到：两次调用静态方法：入参不一样，结果也是不一样的。
