springMVC中遇到的错误，

除了查询，只要是对数据库进行修改的操作，总是成功操作数据到数据库，然后，控制台报错。

就是用这一套东西，来进行一系列操作，

整个系统架构是，springframework+JDBC+tiles.

先贴一段代码，追踪错误的时候，追踪到这里

getMasterTemplate().update(new PreparedStatementCreator() {

 @Override

 public java.sql.PreparedStatement createPreparedStatement(

 java.sql.Connection con) throws SQLException {

 PreparedStatement ps = con.prepareStatement(sql);

 int i = 0;

 ps.setString(++i, circle.getName());

 ps.setLong(++i, circle.getCreateTime());

 return ps;

 });

这里的，

 span getMasterTemplate /span 

是另一段代码，我也贴出来

@Resource(name = "forumTemplate")

 private JdbcTemplate masterTemplate;


要是你问我@resource是什么东西，我只能告诉你，自己去百度spring注解。

然后，我把controller贴出来



@RequestMapping(value = "/del")

 public RetrunValue delCircle(@RequestBody Map String,Object map) {

 long circleId = Long.parseLong( map.get("id").toString());

 try {

 circleService.delete(circleId);

 } catch (Exception e) {

 resultCode=ResultCode.NOT_EXIST;

 return new RetrunValue(resultCode.getCode());

 }

然后就报错了，报错信息如下：



严重: Servlet.service() for servlet [forum] in context with path [/forum] threw exception [Could not resolve view with name pcir/del in servlet with name forum] with root cause

错误日志好多，是不？

而且还没提示是咱们写的代码哪个地方有错。

然后，用debug又追踪不到真正的错误



然后，直觉告诉我，肯定是controller中，什么地方少引用了什么东西。

因为，无论我进行什么操作，总是成功操作到数据库的，然后控制台打印错误。

然后，找到了这个

说的比较含糊，我这里属于第二种原因，方法中，加入了一个注解。@ResponseBody

然后就可以了，成功的代码如下：






@RequestMapping(value = "/del")

 public span style="color: rgb(216, 130, 109); font-family: Hiragino Sans GB W3, Hiragino Sans GB, Arial, Helvetica, simsun, u5b8bu4f53; font-size: 16px; line-height: 28px;" @ResponseBody /span RetrunValue delCircle(@RequestBody Map String,Object map) {

 long circleId = Long.parseLong( map.get("id").toString());

 try {

 circleService.delete(circleId);

 } catch (Exception e) {

 resultCode=ResultCode.NOT_EXIST;

 return new RetrunValue(resultCode.getCode());

 }






  How is correct index.html served by ui5 handler from BSP repository

This wiki explains the process how the index.html of Fiori application is served by UI5 resource handler.

The url of index looks like below:

https://:/sap/bc/ui5_ui5/sap/zfiori150320/index.html?sap-client=001&sap-ui-language=EN&sap-ui-appcache=fal
