鑒于rails的部署太可怕，所以有了使用rails的建表工具和migration，用jfinal來開發的想法，在此貼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"));//設置pgsql的DriverClassc3p0Plugin.setDriverClass("org.postgresql.Driver");c3p0Plugin.start();return c3p0Plugin.getDataSource();}//設置pgsql的Dialect gernerator.setDialect(new PostgreSqlDialect()); gernerator.addExcludedTable("schema_migrations");

?

項目代碼里面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);} }

?
