Maven+spring+spring Mvc+mybatis+mysql, building the SSM framework Environment

Structure after completion of project construction:

The table structure of the database is as follows:

Environment: Build MAVEN environment, Tomcat Environment, need MySQL database support, use programming tools eclipse (these are the preparation);

Start creating a project:

1. Create a MAVEN project:

Select WebApp

Fill it out:

The project will error when the creation is complete:

What's next?

Select Item Right click, select "Properties" to enter the following interface:

Select Project Facets, and then change the Java version to your JDK version, or 1.6 or later.

Then choose Java Build Path

To modify the Java version inside Lib:

Select the JRE System Library above and select Edit

Save and then look at the project. The main operation above is to make the directory structure appear normal. (The above does not necessarily solve the problem, the project will be an error)

Add dependencies in the Pom.xml file:

<dependency>
<groupId>javax</groupId>
<artifactId>javaee-api</artifactId>
<version>7.0</version>
</dependency>

This is immediate;

Then add the dependency package to the Pom file, and the final Pom.xml file is as follows:

Then see if Lib has imported the jar package:

Next you need to configure the following four configuration files in the resource directory structure as follows:

Jdbc.properties, Log4j.properties, Spring-mvc.xml, spring-mybatis.xml These files may all need to be created on their own.

You need to create a database table Testu, including four field IDs username password age

The jdbc.properties configuration is as follows:

jdbc.driver=com.mysql.jdbc.driverjdbc.url=jdbc:mysql://localhost:3306/testu?useunicode=true& Characterencoding=utf-8jdbc.username=rootjdbc.password=root#\u5b9a\u4e49\u521d\u59cb\u8fde\u63a5\ u6570jdbc.initialsize=0#\u5b9a\u4e49\u6700\u5927\u8fde\u63a5\u6570  jdbc.maxactive=20#\u5b9a\u4e49\u6700\ U5927\U7A7A\U95F2  jdbc.maxidle=20#\u5b9a\u4e49\u6700\u5c0f\u7a7a\u95f2jdbc.minidle=1#\u5b9a\u4e49\u6700\ u957f\u7b49\u5f85\u65f6\u95f4jdbc.maxwait=60000

The log4j.properties configuration is as follows:

#定义LOG输出级别log4j. rootlogger=info,console,file# definition Log Output destination to console log4j.appender.console= The org.apache.log4j.consoleappenderlog4j.appender.console.target=system.out# provides the flexibility to specify the log output format, The following line specifies the specific format log4j.appender.Console.layout = ORG.APACHE.LOG4J.PATTERNLAYOUTLOG4J.APPENDER.CONSOLE.LAYOUT.CONVERSIONPATTERN=[%C]-%m%n# When the file size reaches the specified size, a new file is generated log4j.appender.File = org.apache.log4j.rollingfileappender# Specifies the output directory log4j.appender.File.File = logs/ssm.log# definition file Maximum size log4j.appender.File.MaxFileSize = 10mb# output so log, If switching to debug indicates output debug above level log Log4j.appender.File.Threshold = ALLlog4j.appender.File.layout = Org.apache.log4j.PatternLayoutlog4j.appender.File.layout.ConversionPattern =[%p] [%d{yyyy-mm-dd hh\:mm\:ss}][%c]% m%n

The Spring-mvc.xml configuration is as follows:

<?xml version= "1.0" encoding= "UTF-8"? ><beans xmlns= "Http://www.springframework.org/schema/beans" xmlns: Xsi= "Http://www.w3.org/2001/XMLSchema-instance" xmlns:p= "http://www.springframework.org/schema/p" xmlns:context= "Http://www.springframework.org/schema/context" xmlns:mvc= "Http://www.springframework.org/schema/mvc" xsi: schemalocation= "Http://www.springframework.org/schema/beans Http://www.springframework.org/schema                          /beans/spring-beans-3.1.xsd Http://www.springframework.org/schema/context Http://www.springframework.org/schema/context/spring-context-3.1.xsd Http://www.springframework .

Spring-mybatis.xml configuration file:

<?xml version= "1.0" encoding= "UTF-8"? ><beans xmlns= "Http://www.springframework.org/schema/beans" xmlns: Xsi= "Http://www.w3.org/2001/XMLSchema-instance" xmlns:p= "http://www.springframework.org/schema/p" xmlns:context= "Http://www.springframework.org/schema/context" xmlns:mvc= "Http://www.springframework.org/schema/mvc" xsi: schemalocation= "Http://www.springframework.org/schema/beans Http://www.springframework.org/schema                          /beans/spring-beans-3.1.xsd Http://www.springframework.org/schema/context Http://www.springframework.org/schema/context/spring-context-3.1.xsd Http://www.springframework .

Here the configuration file basic configuration is complete

Then how to create a simple instance to run:

You can refer to this article http://blog.csdn.net/cool_easy/article/details/42778239 using code generation. Generated

With these three packages, there are several files that need to be created yourself.

The code structure is as follows
