4.连接:root/root1234
5.运行
SELECT http_post('http://192.168.101.9:8054/udf/test2','a=xoyo333&b=0111111'); ?
192.168.101.9:机器ip地址 8054项目端口??udf/test2接口??a=xoyo333&b=0111111入参
6.java代码:
controller
@RequestMapping("/udf")
@RestController
public class MysqlUdfHttpController {
@Resource
UdfMapper udfMapper;
@RequestMapping("/test2")
public String getMenuList12(String a,String b) {
return a+b;
}
@RequestMapping("/test1")
public List<Menu> test1(@RequestParam long pid) {
String s = udfMapper.httpGets("http://192.168.101.9:8054/udf/test11?pid=1" );
List<Menu> menus = JSONArray.parseArray(s, Menu.class);
return menus;
}
@RequestMapping("/test11")
public List<Menu> test11(@RequestParam long pid) {
List<Menu> menu = menuService.findMenu(pid);
return menu;
}
}
UdfMapper
package com.zq.mybatisexample.mapper;
import org.apache.ibatis.annotations.Mapper;
import org.apache.ibatis.annotations.Param;
import org.apache.ibatis.annotations.Select;
@Mapper
public interface UdfMapper {
@Select("select http_get(#{url}, #{params}) as response from dual")
String httpGet(@Param("url") String url, @Param("params") String params);
@Select("select http_post(#{url}, #{params}) as response from dual")
String httpPost(@Param("url") String url, @Param("params") String params);
@Select("select http_get(#{url}) from dual")
String httpGets(@Param("url") String url );
}
7.测试:
navaicat中运行选择的sql即可调用到 代码中的代码:
8.例子2:实现(? 请求java接口->mysql udf ->? java接口? )
页面请求接口:http://localhost:8054/udf/test1?pid=1
解释:
页面调用:http://localhost:8054/udf/test1?pid=1
然后使用mysql udf的转发功能?
String s = udfMapper.httpGets("http://192.168.101.9:8054/udf/test11?pid=1" );
这一句作用:让mysql udf数据库去调用?
http://192.168.101.9:8054/udf/test11?pid=1 这个接口 ( 可结合使用上方例子1 SELECT http_post('http://192.168.101.9:8054/udf/test2','a=vvv&b=aaaaa'); ? 来理解即可 )
然后test11接口返回数据即可。
