鉴于rails的部署太可怕,所以有了使用rails的建表工具和migration,用jfinal来开发的想法,在此贴一下需要注意的地方
maven配置
<dependency> <groupId>com.jfinal</groupId> <artifactId>jfinal</artifactId> <version>2.2</version> </dependency> <!-- http://mvnrepository.com/artifact/com.mchange/c3p0 --> <dependency> <groupId>com.mchange</groupId> <artifactId>c3p0</artifactId> <version>0.9.5.2</version> </dependency> <!-- http://mvnrepository.com/artifact/org.postgresql/postgresql --> <dependency> <groupId>org.postgresql</groupId> <artifactId>postgresql</artifactId> <version>9.4.1208</version> </dependency>
resources下面的db.config
jdbcUrl = jdbc:postgresql://localhost:5432/my_rails_development user = mmc password = mmc
jfinal的model生成器
public static DataSource getDataSource() { Prop p = PropKit.use("db.config"); C3p0Plugin c3p0Plugin = new C3p0Plugin(p.get("jdbcUrl"), p.get("user"), p.get("password")); //设置pgsql的DriverClass c3p0Plugin.setDriverClass("org.postgresql.Driver"); c3p0Plugin.start(); return c3p0Plugin.getDataSource(); } //设置pgsql的Dialect gernerator.setDialect(new PostgreSqlDialect()); gernerator.addExcludedTable("schema_migrations");
项目代码里面config
public void configPlugin(Plugins me) { Prop p = PropKit.use("db.config"); C3p0Plugin cp = new C3p0Plugin(p.get("jdbcUrl"), p.get("user"), p.get("password"),"org.postgresql.Driver"); cp.start(); me.add(cp); ActiveRecordPlugin arp = new ActiveRecordPlugin(cp); arp.setDialect(new PostgreSqlDialect()); _MappingKit.mapping(arp); me.add(arp); }
HelloController.java
public class HelloController extends Controller { public void index() { List<Users> users = Users.dao.find("select * from users;"); String name = users.get(0).getName(); renderText(name); } }
