1、自己创建的jar包导入本地仓库引用后出现错误
1 [ERROR] [ERROR] Some problems were encountered while processing the POMs: 2 3 [WARNING] 'dependencies.dependency.(groupId:artifactId:type:classifier)' must be unique: org.apache.commons:commons-io:jar -> duplicate declaration of version (?) @ line 66, column 21 4 5 [ERROR] 'dependencies.dependency.version' for fastdfs_client:fastdfs_client:jar is missing. @ line 58, column 21 6 7 @ 8 9 [ERROR] The build could not read 1 project -> [Help 1] 10 11 [ERROR] 12 13 [ERROR] The project cn.thyonline:taotao-common:0.0.1-SNAPSHOT (D:\application\taotao\taotao-common\pom.xml) has 1 error 14 15 [ERROR] 'dependencies.dependency.version' for fastdfs_client:fastdfs_client:jar is missing. @ line 58, column 21 16 17 [ERROR] 18 19 [ERROR] To see the full stack trace of the errors, re-run Maven with the -e switch. 20 21 [ERROR] Re-run Maven using the -X switch to enable full debug logging. 22 23 [ERROR] 24 25 [ERROR] For more information about the errors and possible solutions, please read the following articles: 26 27 [ERROR] [Help 1] http://cwiki.apache.org/confluence/display/MAVEN/ProjectBuildingException
不知道为什么父pom文件里面声明的版本号没有生效，在对应的子pom文件添加版本号之后这个错误就消失了
2、数据MultipartFile在dubbo中传递的错误

检查发现dubbo的引用服务和发布服务的设定都没问题。但是picFile这个方法就是传递不到。这些都没问题，问题只可能是传递的数据MultipartFile不支持dubbo的这种传递方式。于是我把保存图片的方法写到controller层。运行成功~
3、后台无法接收到js传来的数据
1 text:'删除', 2 3 iconCls:'icon-cancel', 4 5 handler:function(){ 6 7 var ids = getSelectionsIds(); 8 9 if(ids.length == 0){ 10 11 $.messager.alert('提示','未选中商品!'); 12 13 return ; 14 15 } 16 17 $.messager.confirm('确认','确定删除ID为 '+ids+' 的商品吗？',function(r){ 18 19 if (r){ 20 21 var params = {"ids":ids}; 22 23 $.post("/rest/item/delete",params, function(data){ 24 25 if(data.status == 200){ 26 27 $.messager.alert('提示','删除商品成功!',undefined,function(){ 28 29 $("#itemList").datagrid("reload"); 30 31 }); 32 33 } 34 35 }); 36 37 } 38 39 }); 40 41 }
改成对应的数据则删除成功，说明在后端接收数据的时候需要指定数据类型和数据的名称，才能正确接收到数据在做删除的功能时，后台使用Long id和string id都无法接收到数据。查看jQuery页面的时候发现页面传到后台的数据为String ids。
