Two. MyBatis Generator (Postgres)-– generates DTO, Dao, Mapping
Because MyBatis belongs to a semi-automatic ORM framework, the main job will be to write the mapping mapping file, but because the handwriting mapping file is prone to error, the data discovery has off-the-shelf tools to automatically generate the underlying model classes, DAO interface classes, and even mapping mapping files.

-– Create a table
CREATE TABLE Worker (
ID varchar not NULL,
Username varchar (km) CHARACTER SET UTF8 COLLATE utf8_bin DEFAULT NULL,
Password varchar (%) DEFAULT NULL,
PRIMARY KEY (ID)
) Engine=innodb DEFAULT Charset=utf-8;

-– Configuration Generator Config
Generatorconfig.xml

<?xml version= "1.0" encoding= "UTF-8"?> <! DOCTYPE generatorconfiguration Public "-//mybatis.org//dtd mybatis generator Configuration" "1.0//en Mybatis.org/dtd/mybatis-generator-config_1_0.dtd "> <generatorConfiguration> <classpathentry locat

-– generation (two ways)
1. Right-click Configuration file to run:

2. Order: Java-jar/users/liqiu/git/study/web/soft/mybatis-generator-core-1.3.2/lib/mybatis-generator-core-1.3.2.jar -configfile/users/liqiu/git/study/web/soft/mybatisgeneratorconfig.xml-overwrite

* Unable to correctly generate look here:
Http://www.cnblogs.com/AloneSword/p/3412236.html

1.XML Parser Error on line 13:xml document structure must be included in the same entity from beginning to beginning.
Looks like the configuration file cannot be commented on.

2.Unexpected error while running MyBatis generator. Exception getting JDBC Driver
Check Generator Official document Discovery specify jar package path

3.eneration warnings occured Table configuration with catalog null, schema NULL, and Table T_login did Tables
Forgot to build the table, no table in the database of course can not resolve ... CREATE TABLE, parse success, no pressure
