基于resty orm的ActiveRecord操作数据指南

##druid plugin auto load，default 为数据源名字
##druid plugin auto load
db.default.url=jdbc:mysql://127.0.0.1/example?useUnicode=true&characterEncoding=UTF-8
db.default.user=dev
db.default.password=dev1010
db.default.dialect=mysql
#c3p0配置
c3p0.default.minPoolSize=3
c3p0.default.maxPoolSize=20
#druid配置
#druid.default.initialSize=10
#druid.default.maxPoolPreparedStatementPerConnectionSize=20
#druid.default.timeBetweenConnectErrorMillis=1000
#druid.default.filters=slf4j,stat,wall
#flyway database migration auto load
flyway.default.valid.clean=true
flyway.default.migration.auto=true
flyway.default.migration.initOnMigrate=true

public void configPlugin(PluginLoader pluginLoader) {
    C3p0DataSourceProvider cdsp = new C3p0DataSourceProvider("default");
    ActiveRecordPlugin activeRecordCdsp = new ActiveRecordPlugin(cdsp, true);
    //映射的model必须能被扫描到 
    activeRecordCdsp.addIncludePaths("cn.dreampie.orm");
    pluginLoader.add(activeRecordCdsp);
}

  //假设cn.dreampie.orm目录下有个model叫User
  //使用table注解来映射指定的数据表，generatedKey是自增主键(自增方式分为数据库自增和自定义生成器自增，如uuid)，primaryKey非自增主键，generated=true 表示使用自定义的生成器生成主键，cached 表示缓存
  @Table(name = "sec_user",generatedKey="id", primaryKey = "sid",generated=true, cached = true)
  public class User extends Model<User> {
    public static User dao = new User();
  }

@API("/users")
public class UserResource extends ApiResource {
  /**
   * 查询一个user的集合
   */
  @GET
  public List<User> findAll() {
    //使用Record 达到相同的效果，而不需要编写User.java
    //Record userDAO＝new Record("sec_user","id,sid",true,true);
    //userDAO.findAll();
    return User.dao.findAll();
  }
}
