JFinal 介绍自行移步到其官网:
http://www.jfinal.com/
简单来说JFinal的定位是接近全栈的 所以我这边硬生生把JOOQ拉进来有点违背他的用意
这篇文章也就当作一个记录好了 以免以后忘记什么东西
环境使用:
- JDK1.8
- Tomcat8
- JFinal 1.8(1.9已经出了 但maven仓库里还没有 我就偷懒用了1.8)
- JOOQ 3.4.4
JOOQ的codegen使用很简单 可以参考官网手册
http://www.jooq.org/doc/3.4/manual-pdf/jOOQ-manual-3.4.pdf
这里不再累述
首先是maven的依赖项:
<dependencies> <dependency> <groupId>mysql</groupId> <artifactId>mysql-connector-java</artifactId> <version>5.1.33</version> </dependency> <dependency> <groupId>org.jooq</groupId> <artifactId>jooq-meta</artifactId> <version>3.4.4</version> </dependency> <dependency> <groupId>com.jfinal</groupId> <artifactId>jfinal</artifactId> <version>1.8</version> </dependency> <dependency> <groupId>org.jooq</groupId> <artifactId>jooq</artifactId> <version>3.4.4</version> </dependency> <dependency> <groupId>org.jooq</groupId> <artifactId>jooq-codegen</artifactId> <version>3.4.4</version> </dependency> <dependency> <groupId>ch.qos.logback</groupId> <artifactId>logback-core</artifactId> <version>1.1.2</version> </dependency> <dependency> <groupId>ch.qos.logback</groupId> <artifactId>logback-access</artifactId> <version>1.1.2</version> </dependency> <dependency> <groupId>ch.qos.logback</groupId> <artifactId>logback-classic</artifactId> <version>1.1.2</version> </dependency> <dependency> <groupId>org.slf4j</groupId> <artifactId>slf4j-api</artifactId> <version>1.7.7</version> </dependency> <dependency> <groupId>com.alibaba</groupId> <artifactId>druid</artifactId> <version>1.0.9</version> </dependency> </dependencies> <build> <finalName>XX</finalName> <pluginManagement> <plugins> <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-compiler-plugin</artifactId> <version>3.2</version> <configuration> <source>1.8</source> <target>1.8</target> </configuration> </plugin> </plugins> </pluginManagement> </build> </project>
logback的配置:
<?xml version="1.0" encoding="UTF-8"?>
<configuration>
<appender name="STDOUT" class="ch.qos.logback.core.ConsoleAppender">
<encoder>
<pattern>%date{yyyy-MM-dd HH:mm:ss ZZZZ} - [%level] - from %logger in %thread %n%message%n%xException%n</pattern>
</encoder>
</appender>
<appender name="FILE"
class="ch.qos.logback.core.rolling.RollingFileAppender">
<file>logs/application.log</file>
<rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
<!-- Daily rollover with compression -->
<fileNamePattern>application-log-%d{yyyy-MM-dd}.gz</fileNamePattern>
<!-- keep 30 days worth of history -->
<maxHistory>30</maxHistory>
</rollingPolicy>
<encoder>
<pattern>%date{yyyy-MM-dd HH:mm:ss ZZZZ} - [%level] - from %logger in %thread %n%message%n%xException%n</pattern>
</encoder>
</appender>
<!-- ingore log -->
<logger name="org.jooq.Constants" level="OFF" />
<logger name="com.alibaba.druid.pool.DruidDataSource" level="OFF" />
<root level="INFO">
<appender-ref ref="STDOUT" />
<appender-ref ref="FILE" />
</root>
</configuration>
web-inf.xml的配置:
<?xml version="1.0" encoding="UTF-8"?> <web-app version="3.1" xmlns="http://xmlns.jcp.org/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd"> <filter> <filter-name>jfinal</filter-name> <filter-class>com.jfinal.core.JFinalFilter</filter-class> <init-param> <param-name>configClass</param-name> <param-value>com.cc.xx.config.Config</param-value> </init-param> </filter> <filter-mapping> <filter-name>jfinal</filter-name> <url-pattern>/*</url-pattern> </filter-mapping> <display-name>Archetype Created Web Application</display-name> </web-app>
Config.java内容:
package com.cc.xx.config;
... ...
public class Config extends JFinalConfig {
@Override
public void afterJFinalStart() {
super.afterJFinalStart();
DBTool.shutDown();
}
@Override
public void beforeJFinalStop() {
super.beforeJFinalStop();
DBTool.getDataSource();
}
@Override
public void configConstant(Constants me) {
me.setDevMode(true);
me.setViewType(ViewType.FREE_MARKER);
}
@Override
public void configRoute(Routes me) {
me.add("/test", Test.class);
}
... ...
}
数据库属性配置:
db.url=jdbc:mysql://localhost:3306/xx db.name=root db.password= ds.initialSize=1 ds.maxActive=20 ds.minIdle=10 ds.maxIdle=15 ds.maxWait=60000 ds.validationQuery=SELECT 'x'
连接池配置:
package com.cc.xx.db;
... ...
public class DBTool {
private static Logger LOG = LoggerFactory.getLogger(DBTool.class);
private volatile static DruidDataSource dataSource;
public static DataSource getDataSource() {
if (dataSource == null) {
synchronized (DBTool.class) {
if (dataSource == null) {
Properties prop = new Properties();
try {
prop.load(DBTool.class.getResourceAsStream("/db.properties"));
} catch (IOException e) {
LOG.error("getDataSource", e);
}
dataSource = new DruidDataSource();
dataSource.setUrl((String) prop.get("db.url"));
dataSource.setUsername((String) prop.get("db.name"));
dataSource.setPassword((String) prop.get("db.password"));
dataSource.setInitialSize(Integer.valueOf((String) prop.get("ds.initialSize")));
dataSource.setMinIdle(Integer.valueOf((String) prop.get("ds.minIdle")));
dataSource.setMaxActive(Integer.valueOf((String) prop.get("ds.maxActive")));
dataSource.setMaxWait(Long.valueOf((String) prop.get("ds.maxWait")));
dataSource.setValidationQuery((String) prop.get("ds.validationQuery"));
}
}
}
return dataSource;
}
public static void shutDown() {
if (dataSource != null) {
dataSource.close();
}
}
}
测试代码:
package com.cc.xx.controller;
... ...
public class Test extends Controller {
public void index() {
List<String> s = DSL.using(DBTool.getDataSource(), SQLDialect.MYSQL).select(FACTORY.ID).from(FACTORY).limit(0, 10)
.fetch(r -> r.getValue(FACTORY.ID));
renderJson(s);
}
}
这样就好了
可以看到这和我在play2和slick2整合一样 是单独使用了连接池 类似一种外挂的形式放到原有框架中去
不过也就是简单的整合 具体使用以后会再补充
