选择版本一定要选择人数最多的合适的版本，最新的版本并不是最好的，我对最新的版本用ssm作了一个测试，发现依赖版本的选择真的很重要，尤其是一下版本

各种要版本如下

笔记如下：

### day0806

* 复习ssm框架的搭建和使用

### 流程

#### 1、搭建框架

* springmvc springioc mybatis,简称ssm

* 搭建springmvc,第一步骤创建项目，

打包方式

* 添加依赖，就是导包

* 配置前端控制器(DispatcherServlet)，

给DispatcherServlet添加配置文件 springmvc.xml

* springmvc.xml开启注解驱动，

* 配置包路径扫描

* 配置视图解析器（jsp模式）

* 写一个controller包下的控制器，测试类（写业务代码）

还有jsp

看见页面了，表示mvc环境行了

* 实现步骤：利用骨架（张老师）

* 问题：Junit用4.12版本以及以上，因为他支持spring-test*******

* 添加的依赖：springweb-mvc,servelt,jsp,jstl,lombok,(springmvc的能够跑起来了),junit(单元测试)

* <scope>作用域，jsp的四大作用域，

provided在main和test好用

Tomcat自己有servlet和jsp

* 用javaweb写的servlet目录最终在na?web/lib

* springmvc.xml放在java中的配置**********

* 一般情况下放在resources,默认编译xml文件

##### springioc

* 目的是使用IOC容器管理各种 bean对象，service,dao,等等

* 配置IOC核心配置文件

* 创建一个applicationContext.xml

* 1、扫描service包

2、service验证成功（依赖注入）

service一个接口，一个实现类

##### mybatis

* 导包

* 数据库引擎，InnoDB支持事务

* 需要导入的包有，mybatis,mybatis-spring,mybatis-orm,druid,mysql,common(一个工具)

* 能够让mapper接口放到IOC容器中管理，

原生：sqlSesssion.getMapper();获取到到对象

sqlSession线程不安全的api,在IOC容器中注入SqlSessionFactory,

sqlsessionFactory需要数据源，

* mybatis-srping

mybatis和spring的桥，SqlSessionFactoryBean

原来的不方便IOC容器管理，他依赖了orm，所以得引入

mybatis-orm,得自己手动导入**************

* 数据源：druid

common (lang log4j ...都在)

配置数据源，在IOC容器中，配置sqlSessionFactoryBean,配置

让ioc容器管理Maper代理对象

ref引用的是对象

配置别名，TypeAlisesPackage

配置让IOC容器管理的的Mapper代理

* 声明一个Mapper接口和Mapper.xml***************

pojo,

其中对应一致，UserDao和UserDao.xml(包名对应一致)

其中namespace是接口的全限定名字************

* 写* 需要在mysql服务器需要转换成字段枚举，其中* 的效率不高，不建议使用；***********

* 其中Mapper代理对象需要包扫描， basePackage,

* 测试：

### 测试，使用MockMVC

* 方便我们做测试

* 写一个单元测试类

* ognl表达式，在structs2 的标签中使用的比较多。（语法的类库）， #{username}

对于web.xml中配置DispatchetServlet中param-name报错的问题，纯粹是测试jar包版本中懒得写直接cv了，然后发现报错了，神奇，百度后发现居然是web.xml你必须自己写，不要cv,不然会报错，cv后解决方案如图：

ssm整合至版本之谜+CVweb.xml报错的解决方法+笔记+mockMvc使用+实训+day0806

对于web.xml和springmvc.xml和application.xml在上篇已经发布了，下面对于mockMvc工具的使用

package com.neuedu.controller;

import org.springframework.test.web.servlet.result.MockMvcResultMatchers;
import org.springframework.test.web.servlet.setup.MockMvcBuilders;
import org.springframework.web.context.WebApplicationContext;


import static org.junit.Assert.*;

@RunWith(SpringJUnit4ClassRunner.class)
//注入webapplication
@WebAppConfiguration()
//找到spring的配置文件
@ContextConfiguration({"classpath:mvc/springmvc.xml","classpath:applicationContext.xml"})

public class UserTestTest {

    private MockMvc mockMvc;

    @Autowired
    private WebApplicationContext wac;

    @Before
    public void setUp() throws Exception {
        mockMvc = MockMvcBuilders.webAppContextSetup(wac).build();
    }

    @Test
    public void list() throws Exception {
        String url ="http://localhost/test/list";

        MvcResult result = mockMvc.perform(MockMvcRequestBuilders.get(url)).
                andExpect(MockMvcResultMatchers.status().isOk()).andReturn();

        System.out.println(result.getResponse().getContentAsString());
    }

    @Test
    public void add() throws Exception {
        String url ="http://localhost/test/add";

        MockHttpServletRequestBuilder mockHttpServletRequestBuilder = MockMvcRequestBuilders.get(url);
        System.out.println(mockHttpServletRequestBuilder+"****************8");
        ResultActions perform = mockMvc.perform(mockHttpServletRequestBuilder);
        System.out.println(perform+"66666666666666666666666666");
//        MvcResult result = mockMvc.perform(
//                MockMvcRequestBuilders.get(url)
//                .param("username","兔子")
//                .param("password","123434")
//        ).
//                andExpect(MockMvcResultMatchers.status().isOk()).andReturn();
//
//        System.out.println(result.getResponse().getContentAsString());
    }
