两个项目之间通过 RestTemplate 进行调用

时间:2021-03-28 20:13:35

A服务发出请求:

@RequestMapping("/jqgridjsondata.json")
@ResponseBody
public String jqgridJsonData(HttpServletRequest request) {

    String laglms_service_method = "test/gettestentityset";
    String serviceaddr = String.format("%s:%s/%s", LAGLMS_SERVICE_URI, LAGLMS_SERVICE_PORT, laglms_service_method);

    return restTemplate.postForObject(serviceaddr, requestConvert(request), String.class);
}

/**
 * 转换请求以适用于rest template.
 *
 * @param request http sevlet request.
 * @return multivaluemap.
 */
private MultiValueMap<String, Object> requestConvert(HttpServletRequest request) {
    MultiValueMap<String, Object> parameterMap = new LinkedMultiValueMap<>();
    HttpHeaders headers = new HttpHeaders();
    headers.add("Content-Type", "application/x-www-form-urlencoded");
    HttpEntity<MultiValueMap<String, Object>> r = new HttpEntity<>(parameterMap, headers);
    for (Map.Entry<String, String[]> entry : request.getParameterMap().entrySet()) {
        parameterMap.add(entry.getKey(), entry.getValue()[0]);
    }
    return parameterMap;
}

 

B服务接收:

package com.thunisoft.laglms.controller;

import com.thunisoft.laglms.pojo.JQGridPojo;
import com.thunisoft.laglms.pojo.TestEntityPojo;
import com.thunisoft.laglms.service.TestService;
import com.thunisoft.maybee.engine.db.feature.PageInfo;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.ResponseBody;

@Controller
@RequestMapping("/test")
public class TestController {

    @Autowired
    private TestService testService;

    @RequestMapping("/gettestentityset")
    @ResponseBody
    public JQGridPojo getTestEntitySet(TestEntityPojo queryvo, PageInfo pageInfo) {
        JQGridPojo jqGridPojo = testService.getTestEntitySet(queryvo, pageInfo);
        return jqGridPojo;
    }
}
