SSM (springmvc+mybatis+spring) Java Web construction Project __ "Development tools" ECLIPSE-J2EE

No.1 first built the Web engineering structure. Introduction to 1.1.1 development environment

Here I am using the MySQL database

The compiler version uses the JDK for 1.8

The development tool is using the Eclipse Mars version

The Web container uses a Tomcat version of version 7.0

Here I will write my own demo project directory structure screenshot to show the convenience of everyone new projects

This picture clearly shows my project clearly, first of all, a brief introduction, the project main package begins with Com.cntv. Below it is divided into several sub packages, namely Mapper, Controller, Service, DAO, Mapper, Logs, Config, base, entity, test package, Where the controller package is responsible for receiving the front request to perform part of the business logic of the action, familiar with the struts framework should know the action ha here I do not say in detail.  The mapper package is primarily responsible for mybatis framework entity mappings, which are the primary storage project configuration files. Other packages are not covered, they are regular packages.

No.2 ready for the appropriate Jar pack here I am using Spring is. 2.0 version MyBatis is a 3.3.0 version of the box selected jar package is a few dependencies jar pack don't think this is the complete jar pack and ....

So far, the jar pack is ready to start. Prepare the related configuration of the framework first is the Spring+mybatis associated configuration no.3 configuration framework related features of the configuration file

Create a new Spring-mybatis.xml file in the Config folder in the SRC directory and integrate and correlate the Spring+mybatis framework through this file
