spring boot学习第十三篇:使用jsonrpc
因为我学习spring boot会有很多内容，所以和spring boot有关的文章使用的pom.xml和application.yml这2个文件的内容就全列出来，不用再单独抽出来了，单独抽出来有点麻烦也不方便学习。
1、pom.xml文件内容如下：

2、application.yml文件内容如下：
server:
port: 8081
servlet.context-path: /
#配置数据源
spring:
datasource:
druid:
db-type: com.alibaba.druid.pool.DruidDataSource
driverClassName: net.sf.log4jdbc.sql.jdbcapi.DriverSpy
url: jdbc:log4jdbc:mysql://${DB_HOST:localhost}:${DB_PORT:3306}/${DB_NAME:eladmin}?serverTimezone=Asia/Shanghai&characterEncoding=utf8&useSSL=false
username: ${DB_USER:root}
password: ${DB_PWD:demo}
redis:
host: localhost
port: 6379
password: demo
database: 10
data:
mongodb:
host: 43.138.0.199
port: 27017
username: hmblogs
password: demo
database: hmblogs
authentication-database: admin
es:
host: 43.138.0.199
port: 9200
scheme: http
user: elastic
password: demo3、启动类BackendApplication内容如下：
package com.hmblogs.backend;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
@SpringBootApplication
public class BackendApplication {
public static void main(String[] args) {
SpringApplication.run(BackendApplication.class, args);
}
}
4、接口类AcceptSignedAPI内容如下：
package com.hmblogs.backend.jsonRpc;
import com.googlecode.jsonrpc4j.JsonRpcService;
@JsonRpcService(value = "acceptSigned")
public interface AcceptSignedAPI {
public void acceptSigned(Object o);
}
5、接口实现类AcceptSignedImpl内容如下：
package com.hmblogs.backend.jsonRpc;
import com.googlecode.jsonrpc4j.spring.AutoJsonRpcServiceImpl;
import org.springframework.stereotype.Service;
@Service
@AutoJsonRpcServiceImpl
public class AcceptSignedImpl implements AcceptSignedAPI {
@Override
public void acceptSigned(Object o) {
System.out.println("222"+o);
}
}
6、工具类RpcClientUtil内容如下：
package com.hmblogs.backend.jsonRpc;
import com.googlecode.jsonrpc4j.JsonRpcHttpClient;
import java.net.URL;
/**
* address:要送数据到哪个地址
* params : json数据
* methodName: 接口的方法名字
*/
public class RpcClientUtil {
public static String postJsonRPC(String address, Object params, String methodName) throws Throwable {
URL url = null;
JsonRpcHttpClient jsonRpcHttpClient = null;
String result = null;
try {
url = new URL(address);
jsonRpcHttpClient = new JsonRpcHttpClient(url);
result = jsonRpcHttpClient.invoke(methodName, params, String.class);
} catch (Exception e) {
throw e;
} finally {
url = null;
jsonRpcHttpClient = null;
}
return result;
}
}
7、测试类RpcTest内容如下：
package com.hmblogs.backend.jsonRpc;
import com.alibaba.fastjson.JSONArray;
import com.alibaba.fastjson.JSONObject;
import org.junit.Test;
public class RpcTest {
@Test
public void sendRpc() throws Throwable {
JSONObject jsonO = new JSONObject();
jsonO.put("name","hem");
jsonO.put("sex","nan");
JSONArray jsonArray = new JSONArray();
jsonArray.add(jsonO);
RpcClientUtil.postJsonRPC("http://127.0.0.1:8081/acceptSigned", "[{\"sex\":\"nan\",\"name\":\"1111\"}]","acceptSigned");
}
}
然后报错了，文件结构、运行方法、报错整体截图如下：
报错内容如下：
