Could not resolve view with name 'pcir/del' in servlet with name 'forum'

惯例：

我是温浩然：

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;
			}
		});

<span style="font-family: Arial, Helvetica, sans-serif;">getMasterTemplate</span>

@Resource(name = "forumTemplate")
    private JdbcTemplate masterTemplate;
    

    protected JdbcTemplate getMasterTemplate() {
        return 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());
	}

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

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

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());
	}
