Maven项目在Spring3整合Hibernate4框架整合好了之后，写好action、service和Dao之后，编译成功后放入TOMCAT发布，准备用WEB方式访问结果
项目启动报错

主要原因是找不到类
java.lang.ClassNotFoundException: org.springframework.web.context.request.async.CallableProcessingInterceptor
原因是没有导入spring-web包
于是在pom.xml中配置好spring-web重新启动
org.springframework spring-web 3.2.11.RELEASE
但是启动后还是报错

像这种类型的错误
java.io.FileNotFoundException: class path resource [spring.xml] cannot be opened because it does not exist
一般造成原因是jar包冲突
检查pom.xml文件
处理好重复导入的jar包后
重新编译发布，项目启动成功
测试成功
public void add(){ Tuser t = new Tuser(); t.setId(UUID.randomUUID().toString()); t.setName("程凯222"); t.setPwd("456"); t.setCreatedatetime(new Date()); userService.save(t); }
