1、测试数据库

DROP TABLE IF EXISTS `tb_dept`;
CREATE TABLE `tb_dept`  (
  `deptno` tinyint(2) UNSIGNED NOT NULL  COMMENT '部门编号',
  `dname` varchar(14) CHARACTER SET utf8 COLLATE utf8_general_ci NULL DEFAULT NULL COMMENT '部门名称',
  `loc` varchar(13) CHARACTER SET utf8 COLLATE utf8_general_ci NULL DEFAULT NULL COMMENT '部门地址',
  PRIMARY KEY (`deptno`) USING BTREE
) ENGINE = InnoDB  CHARACTER SET = utf8 COLLATE = utf8_general_ci ROW_FORMAT = Dynamic;

INSERT INTO `tb_dept` VALUES (10, 'ACCOUNTING', 'NEW YORK');
INSERT INTO `tb_dept` VALUES (20, 'RESEARCH', 'DALLAS');
INSERT INTO `tb_dept` VALUES (30, 'SALES', 'CHICAGO');
INSERT INTO `tb_dept` VALUES (40, 'OPERATIONS', 'BOSTON');

-------------------------------------------------------------------
DROP TABLE IF EXISTS `tb_emp`;
CREATE TABLE `tb_emp`  (
  `empno` int(4) UNSIGNED NOT NULL,

  CONSTRAINT `tb_emp_ibfk_1` FOREIGN KEY (`deptno`) REFERENCES `tb_dept` (`deptno`) ON DELETE RESTRICT ON UPDATE RESTRICT
) ENGINE = InnoDB CHARACTER SET = utf8 COLLATE = utf8_general_ci ROW_FORMAT = Dynamic;

INSERT INTO `tb_emp` VALUES (7369, 'SMITH', 'CLERK', 7902, '1980-12-17', 800.00, NULL, 20);

INSERT INTO `tb_emp` VALUES (7782, 'CLARK', 'MANAGER', 7839, '1981-06-09', 2450.00, NULL, 10);
INSERT INTO `tb_emp` VALUES (7788, 'SCOTT', 'ANALYST', 7566, '1987-04-19', 3000.00, NULL, 20);

INSERT INTO `tb_emp` VALUES (7934, 'MILLER', 'CLERK', 7782, '1982-01-23', 1300.00, NULL, 10);

2、运行程序

运行App.java中的main方法： 生成的代码的目录结构：

3、使用生成的代码

• 1）创建一个Dynamic Web项目，然后将上面生成的代码按如下所示拷贝进去，同时设置resources为resouce folder：

• 2）将代码生成器中的jar包拷贝到新创建的项目中：

• 2）在新创建的项目中就可以使用生成的代码编写程序了。
