小编Mil*_*lla的帖子

我有两个插件,我想在事务控制下.如果其中一个失败,另一个也不会被执行/插入.这样在MySQL中正确执行时工作正常

START TRANSACTION;
INSERT INTO table (field) VALUES (value);
INSERT INTO table2 (field) VALUES (value);
COMMIT;

现在使用骆驼我已经尝试过了

<to uri="sql:START TRANSACTION; INSERT INTO table (field) VALUES (value);INSERT INTO table2 (field) VALUES (value);COMMIT;"/>

这会产生sql语法错误.我尝试的第二件事是

<to uri="sql:START TRANSACTION"/>
<to uri="sql:INSERT INTO table (field) VALUES (value)"/>
<to uri="sql:INSERT INTO table2 (field) VALUES (value)"/>
<to uri="sql:COMMIT"/>

哪个工作但如果一个插入失败,另一个插入仍在执行和插入.

我也找到了这个 http://camel.apache.org/transactional-client.html,但我使用的是蓝图,这些例子似乎只适用于春天.因此,如果有人用骆驼蓝图做了一个很好的例子,这将是很好的.

任何人都可以帮我在骆驼做这个吗？

当我向我的网络服务发送请求（使用 apache camel 构建并在 apache karaf 上运行）时，我总是得到

<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
 <soap:Body>
  <soap:Fault>
     <faultcode>soap:Client</faultcode>
     <faultstring>Message part {http://localhost:8181/cxf/webservices/inputoutput}input was not recognized.  (Does it exist in service WSDL?)</faultstring>
  </soap:Fault>
 </soap:Body>
</soap:Envelope>

我的 wsdl 看起来像这样

我是 Apache camel 的新手，只是尝试使用 RouteBuilder 构建一条 Route，但是一旦我得到一个扩展 RouterBuilder 的类，当我尝试在 Apache karaf 中安装该包时，就会收到此错误：
