一、SpringMVC

File->New->maven->webapp

解决maven加载过慢问题：

archetypeCatalog
internal

 

在main下面创建文件夹：

Java :右键->make directory as->Test Sources Boot

 

Resources : 右键->make directory as->Test resources Boot

 

 

刷新项目：

右键->maven->Reimport

 

服务器部署：

流程总结：

 

 

 

1、注解的使用：

@Controller  控制层

@Controller用于标记在一个类是控制类，使用它标记的类就是一个SpringMvc Controller对象，不需要再实现Controller接口

@Autowired

@RequestMapping

标记在方法上，使该方法成为一个请求处理方法，会在程序接受到对应请求的URL请求时被调用

Idea创建maven

 

缺少webapp目录的解决方法：

https://www.cnblogs.com/oldzhang1222/p/10429827.html

部署tomcat

https://blog.csdn.net/daxia_2016/article/details/81265282

Information:Internal caches are corrupted or have outdated format, forcing project rebuild等拒绝访问异常之处理办法：

如果是MAVEN项目的话看能不能在IDEA的Terminal里面，在最底下的菜单栏中点击打开，输入指令 MVN CLEAN（前提是配置了环境变量）。

如果不能删除的话，那么就需要手动删除了，这个时候找到你的trunk文件找到target目录手动删除即可。

然后如图所示，删除掉IDEA的缓存，重启IDEA后重新编译项目便可解决。

Idea创建SSM web项目：

https://www.cnblogs.com/xiaofeng88/p/10353152.html

部署jar包：

https://www.cnblogs.com/kongxiaoshuang/p/10689564.html

 

2、拦截器和过滤器的区别：

    过滤器是servlet规范中的一部分，任何java web工程都可以使用

    拦截器是springMVC框架自己的，只有使用springMVC框架的工程才使用

    过滤器在url-pattern中配置了/*之后，可以对所有要访问的资源拦截

    拦截器它是只会拦截访问的控制器方法，如果访问的是jsp，html，css，image或者js是不会进行拦截的

   

 

 

二、SSM整合

ssm各package的含义

https://www.cnblogs.com/yanxi1900/p/8533562.html

持久层：DAO层（mapper）

主要是做数据持久层的工作，负责与数据库进行联络

         Dao层的设计首先设计DAO的接口

         然后在spring的配置文件中定义此接口的实现类

业务层：Service层

         主要负责业务模块的逻辑应用设计

         首先设计接口，再设计实现的类

表现层：Controller层

         负责具体的业务模块流程的控制

         调用service层的接口来控制业务流程

View层：

         与控制层结合比较紧密，主要实现jsp页面

 

1、整合思路： view                    service                 dao

 

三层分别测试，再整合

 

2、搭建环境：

 

创建数据库：

create database ssm;

use ssm;

create table account(

id int primary key auto_increment,

name varchar(20),

money double

);

 

创建maven

 

 

 

 

 

 

添加标签（+）：

archetypeCatalog
internal

测试spring框架:

配置applicationContext.xml

配置web.xml

配置log4j.properties

测试springmvc框架

配置springmvc.xml

部署tomcat

 

 

 

 

 

 

 

 

 

 

 

Spring整合springmvc

整合思路：

 

 

 

Spring整合mybatis:

配置mybatis-config.xml

右键->new->file->mybatis-config.xml

 

 

有关页面跳转的若干问题解决：

 

1、 WEB-INF外跳入外：

只需要<a href=”xx.jsp”>

2、 WEB-INF外跳入内：

需要加上类名上的RequestMapping（“/xx”）

和方法上的RequestMapping（“/yy”）

3、 WEB-INF内跳入外：

需要重定向：return “redirect:/xx”

4、 WEB-INF内跳入内：

直接加上方法上的RequestMapping（“/aa“）

    即可，不必加类上的

 

 注：以上为个人总结，如有错误和不足，请多指教
