ff4j web console 配置说明

web console 可以让我们方便的通过界面管理ff4j，以下是一些简单的说明
详细参考github 文档

spring boot 集成

• pom.xml

    </build>

</project>

• 配置
  application.properties 文件
  添加了jdbc datasource

 

spring.datasource.name=ff4j_db

spring.datasource.url=jdbc:mysql://localhost:3306/ff4j_v1

spring.datasource.driverClassName=com.mysql.jdbc.Driver

spring.datasource.username=root

spring.datasource.password=dalongrong

spring.datasource.driver-class-name=com.mysql.jdbc.Driver

• servlet 配置
  主要是关于web console 的servlet 配置
  FF4jServletConfig.java

 

package com.dalong;

​

import org.ff4j.FF4j;

import org.ff4j.spring.boot.autoconfigure.FF4JConfiguration;

import org.ff4j.web.FF4jDispatcherServlet;

import org.ff4j.web.embedded.ConsoleServlet;

import org.springframework.boot.autoconfigure.AutoConfigureAfter;

import org.springframework.boot.autoconfigure.condition.ConditionalOnClass;

import org.springframework.boot.autoconfigure.condition.ConditionalOnMissingBean;

import org.springframework.boot.web.servlet.ServletRegistrationBean;

import org.springframework.boot.web.support.SpringBootServletInitializer;

import org.springframework.context.annotation.Bean;

import org.springframework.context.annotation.Configuration;

​

@Configuration

@ConditionalOnClass({ConsoleServlet.class, FF4jDispatcherServlet.class})

@AutoConfigureAfter({FF4JConfiguration.class})

public class FF4jServletConfig

        extends SpringBootServletInitializer

{

    @Bean

    public ServletRegistrationBean ff4jDispatcherServletRegistrationBean(FF4jDispatcherServlet ff4jDispatcherServlet)

    {

        return new ServletRegistrationBean(ff4jDispatcherServlet, new String[] { "/ff4j-web-console/*" });

    }

​

    @Bean

    @ConditionalOnMissingBean

    public FF4jDispatcherServlet getFF4jDispatcherServlet(FF4j ff4j)

    {

        FF4jDispatcherServlet ff4jConsoleServlet = new FF4jDispatcherServlet();

        ff4jConsoleServlet.setFf4j(ff4j);

        return ff4jConsoleServlet;

    }

} 

• spring boot 入口
  Application.java 注意对于jdbc DataSource 通过bean 的覆盖方式处理

 

package com.dalong;

​

import net.bytebuddy.asm.Advice;

import org.ff4j.FF4j;

import org.ff4j.springjdbc.store.EventRepositorySpringJdbc;

import org.ff4j.springjdbc.store.FeatureStoreSpringJdbc;

import org.ff4j.springjdbc.store.PropertyStoreSpringJdbc;

import org.springframework.beans.factory.annotation.Autowired;

import org.springframework.boot.CommandLineRunner;

import org.springframework.boot.SpringApplication;

import org.springframework.boot.autoconfigure.SpringBootApplication;

import org.springframework.context.annotation.ComponentScan;

​

import javax.sql.DataSource;

​

@SpringBootApplication

@ComponentScan(value = {"org.ff4j.spring.boot.web.api", "org.ff4j.services", "org.ff4j.aop", "org.ff4j.spring","com.dalong"})

public class Application implements CommandLineRunner {

    @Autowired

    private DataSource dataSource;

​

    @Autowired

    FF4j ff4j;

​

    public static void main(String[] args) {

        SpringApplication.run(Application.class);

    }

    @Override

    public void run(String... strings) throws Exception {

            ff4j.setFeatureStore(new FeatureStoreSpringJdbc(dataSource));

            ff4j.setPropertiesStore(new PropertyStoreSpringJdbc(dataSource));

            ff4j.setEventRepository(new EventRepositorySpringJdbc(dataSource));

            ff4j.audit(true);

            ff4j.autoCreate(true);

    }

}

 

运行效果

• 启动docker-compose for mysql
  mysql数据库

 

docker-compose up -d  

• 启动应用

mvn spring-boot:run

• 效果
