SSM Framework Building (iii) database creation and MyBatis generators automatically generate entity classes, DAO interfaces, and Mapping mapping files

One: Create a database

Create a student table

DROP TABLE IF EXISTS' Student '; CREATE TABLE' Student ' (' ID ')int( One) not NULLauto_increment, 'user_name`varchar( +) not NULL, ' password 'varchar(255) not NULL, ' age 'int(4) not NULL,    PRIMARY KEY(' id ')) ENGINE=InnoDB auto_increment=2 DEFAULTCHARSET=UTF8;Insert   into' Student ' (' id ', 'user_name', ' password ', ' age ')Values(1,'Mai Mai','123456', -);

Two:

Configure Generatorconfig.xml

<?XML version= "1.0" encoding= "UTF-8"?>  <!DOCTYPE generatorconfiguration Public "-//mybatis.org//dtd mybatis Generator Configuration 1.0//en" "Http://myba Tis.org/dtd/mybatis-generator-config_1_0.dtd ">  <generatorconfiguration>  <!--Database-driven -      <Classpathentry Location= "Mysql-connector-java-5.1.25-bin.jar"/>      <ContextID= "Db2tables"Targetruntime= "MyBatis3">          <Commentgenerator>              < Propertyname= "Suppressdate"value= "true"/>              <!--whether to remove automatically generated comments true: Yes: false: No -              < Propertyname= "Suppressallcomments"value= "true"/>          </Commentgenerator>          <!--database link URL, user name, password -          <jdbcconnectionDriverclass= "Com.mysql.jdbc.Driver"Connectionurl= "Jdbc:mysql://127.0.0.1/maimai"userId= "Maimai"Password= "123456">          </jdbcconnection>          <Javatyperesolver>              < Propertyname= "Forcebigdecimals"value= "false"/>          </Javatyperesolver>          <!--Build the package name and location of the model -          <JavamodelgeneratorTargetpackage= "Com.maimai.pojo"Targetproject= "src">              < Propertyname= "Enablesubpackages"value= "true"/>              < Propertyname= "Trimstrings"value= "true"/>          </Javamodelgenerator>          <!--Build the package name and location of the mapping file -          <SqlmapgeneratorTargetpackage= "Com.maimai.mapping"Targetproject= "src">              < Propertyname= "Enablesubpackages"value= "true"/>          </Sqlmapgenerator>          <!--generate DAO's package name and location -          <Javaclientgeneratortype= "Xmlmapper"Targetpackage= "Com.maimai.IDao"Targetproject= "src">              < Propertyname= "Enablesubpackages"value= "true"/>          </Javaclientgenerator>          <!--the table TableName to be generated is the name of the table or view in the database Domainobjectname is the entity class name -          <TableTableName= "user_t"Domainobjectname= "User"Enablecountbyexample= "false"Enableupdatebyexample= "false"Enabledeletebyexample= "false"Enableselectbyexample= "false"Selectbyexamplequeryid= "false"></Table>    </Context>  </Generatorconfigurati

You can now build the

CD H:\mybatis-generator-core-1.3.2\lib

H:

Java-jar Mybatis-generator-core-1.3.2.jar-configfile Generatorconfig.xml-overwrite

Open and look, the build succeeds

Then copy the COM folder and put it here.

The creation of the database and the generation of the class are finished here, and the next step is to start Springmvc and MyBatis configuration
