SpringMVC框架学习（2）--SpringMVC和Mybatis的整合的相关文章

SpringMVC框架学习笔记（1）——HelloWorld

搭建SpringMVC框架 1.添加jar包 jsp-api.jar servlet-api.jar jstl.jar commons-logging-1.1.1.jar spring-beans-4.1.6.RELEASE.jar spring-context-4.1.6.RELEASE.jar spring-core-4.1.6.RELEASE.jar spring-expression-4.1.6.RELEASE.jar spring-tx-4.1.6.RELEASE.jar spring

SpringMVC框架学习笔记（二）

6. 源码分析(了解) 通过前端控制器源码分析springmvc的执行过程. 第一步:前端控制器接收请求 调用doDispatch 第二步:前端控制器调用处理器映射器查找 Handler 第三步:调用处理器适配器执行Handler,得到执行结果ModelAndView 第四步:视图渲染,将model数据填充到request域. 视图解析,得到view: 调用view的渲染方法,将model数据填充到request域 渲染方法: 7. 入门程序小结 通过入门程序理解springmvc前端控制器.处

SpringMVC框架学习

Spring MVC 通过一套 MVC 注解,可以让 POJO 成为处理请求的控制器,无须实现任何接口 1. 搭建环境: 1). 加入 jar 包: commons-logging-1.1.1.jar spring-aop-4.0.0.RELEASE.jar spring-beans-4.0.0.RELEASE.jar spring-context-4.0.0.RELEASE.jar spring-core-4.0.0.RELEASE.jar spring-expression-4.0.0.RE

SpringMVC框架学习笔记（4）——结果跳转方式

1.设置ModelAndView对象.根据View和视图解析器跳转到指定页面(视图解析器前缀+viewname+视图解析器后缀) @Override public ModelAndView handleRequest(HttpServletRequest req, HttpServletResponse resp) throws Exception { ModelAndView mv = new ModelAndView(); mv.setViewName("hello"); mv.a

SpringMVC框架学习笔记（2）——使用注解开发SpringMVC

1.配置web.xml <servlet> <servlet-name>mvc</servlet-name> <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> <init-param> <param-name>contextConfigLocation</param-name> <param-v

Java SpringMVC框架学习（三）springMVC的执行流程

具体执行逻辑如下: 浏览器提交请求到中央调度器. 中央调度器将请求转给处理器映射器. 处理器映射器根据请求, 找到请求对应的处理器, 并将其封装为处理器执行链返回给中央调度器. 中央调度器根据处理器执行链中的处理器, 找到能够执行该处理器的适配器. 适配器调用执行处理器. 处理器将处理结果以及要跳转的视图封装到一个对象ModelAndView中, 并将其返回给处理器适配器. 适配器将结果返回给中央调度器. 中央调度器调用视图解析器, 将ModelAndView中的视图名封装为视图对象. 视图解析

SpringMVC框架学习笔记（3）——controller配置汇总

1.通过URL对应bean <!-- 配置handlerMapper 映射器 --> <bean class="org.springframework.web.servlet.handler.BeanNameUrlHandlerMapping"/> <!-- 配置Controller 自定义控制器 --> <bean name="/hello.do" class="cn.sxt.controller.HelloCo

SpringMVC框架学习笔记——各种异常、报错解决

1.Target runtime com.genuitec.runtime.generic.jee60 is not defined. 找到导入项目的.setting文件夹org.eclipse.wst.common.project.facet.core.xml文件 删除<runtime name="com.genuitec.runtime.generic.jee60"/>这一段 2.Implementation of project facet jst.web.jstl

Java SpringMVC框架学习（二）httpServeltRequest和Model传值的区别

为什么大多程序在controller中给jsp传值时使用model.addAttribute()而不使用httpServeletRequest.setAttribute()? 事实上model数据,最终spring也是写到HttpServletRequest属性中,只是用model更符合mvc设计,减少各层间耦合. @RequestMapping(value="/list",method=RequestMethod.GET) public String list(Model model
