## 扩展模块
|
|||
|
|
|||
|
### pojo生成功能
|
|||
|
|
|||
|
#### 功能简介
|
|||
|
|
|||
|
  pojo生成功能是基于screw延伸出的扩展模块,目前处于初步开发的状态。在日常的开发中,经过需求分析、建模之后,往往会先在数据库中建表,其次在进行代码的开发。那么pojo生成功能在这个阶段就可以帮助大家节省一些重复劳动了。使用pojo生成功能可以直接根据数据库生成对应的java pojo对象。这样后续的修改,开发都会很方便。
|
|||
|
|
|||
|
#### 数据库支持
|
|||
|
|
|||
|
- [x] MySQL
|
|||
|
|

|
|

## 常见问题
|
|||
|
|
|||
|
+ 生成后文档乱码?
|
|||
|
|
|||
|
MySQL:URL加入`?characterEncoding=UTF-8`。
|
|||
|
|
|||
|
+ Caused by: java.lang.NoSuchFieldError: VERSION_2_3_30?
|
|||
|
|
|||
|
检查项目`freemarker`依赖,这是由于版本过低造成的,升级版本为`2.3.30`即可。
|
|||
|
|
|||
|
+ java.lang.AbstractMethodError: oracle.jdbc.driver.T4CConnection.getSchema()Ljava/lang/String;
|
|||
|
|
|||
|
这是因为oracle驱动版本过低造成的,删除或屏蔽目前驱动版本,驱动添加升级为以下版本:
|
|||
|
|
|||
|
``` xml
|
|||
|
<dependency>
|
|||
|
<groupId>com.oracle.ojdbc</groupId>
|
|||
|
<artifactId>ojdbc8</artifactId>
|
|||
|
<version>19.3.0.0</version>
|
|||
|
</dependency>
|
|||
|
<dependency>
|
|||
|
<groupId>cn.easyproject</groupId>
|
|||
|
<artifactId>orai18n</artifactId>
|
|||
|
<version>12.1.0.2.0</version>
|
|||
|
</dependency>
|
|||
|
```
|
|||
|
|
|||
|
+ MySQL数据库表和列字段有说明、生成文档没有说明?
|
|||
|
|
|||
|
URL链接加入`useInformationSchema=true`即可。
|
|||
|
|
|||
|
+ java.lang.AbstractMethodError: com.mysql.jdbc.JDBC4Connection.getSchema()Ljava/lang/String;
|
|||
|
|
|||
|
这是因为mysql驱动版本过低造成的,升级mysql驱动版本为最新即可。
