Http 访问SAP RFC函数工具类
最近公司需要将SAP RFC函数接口提供给第三方,但是很多第三方对于RFC函数的对接都不适应，产生了很多对接上的问题。
最终考虑通过Http直接访问SAP RFC函数，这样将难懂的SAP RFC 转换成了识别度高的Http,和第三方对接时,也是省事不少。
直蹦主题,上码。
输入参数
/**
* sap参数
*/
@Data
public class SapParamDto {
private String clientId; //所属系统号
private String functionName;
private Map<String,Object> inputParam; //输入参数
private Map<String,Map<String,Object>> inputStruct; //输入结构体参数
private Map<String,List<Map<String,Object>>> inputTable; //输入table参数
private List<String> outputParam; //输出参数
private Map<String,List<String>> outputStruct; //输出结构体参数
private Map<String,List<String>> outputTable; //输出table参数
}
配置参数SapConfig
@Component
@ConfigurationProperties(prefix = "sap.config")
@Data

private String host;
private String sysnr;

输出参数
@Data

private Map<String,Object> outputMap; //输出参数
private Map<String,Map<String,Object>> outputStruct; //输出结构体参数
private Map<String, List<Map<String,Object>>> outputTable; //输出table参数
