注册中心

 

ZookeeperConfiguration：zookeeper配置

public final class ZookeeperConfiguration {
    private final String serverLists;
    private final String namespace;
    private int baseSleepTimeMilliseconds = 1000;
    private int maxSleepTimeMilliseconds = 3000;
    private int maxRetries = 3;
    private int sessionTimeoutMilliseconds;
    private int connectionTimeoutMilliseconds;
    private String digest;

    public ZookeeperConfiguration(String serverLists, String namespace) {
        this.serverLists = serverLists;
        this.namespace = namespace;
    }

 

ZookeeperRegistryCenter：作业注册中心配置

public final class ZookeeperRegistryCenter implements CoordinatorRegistryCenter {

********
构造函数

    public ZookeeperRegistryCenter(ZookeeperConfiguration zkConfig)


********
常用方法

    public void init()    //初始化注册中心
    public void close()   //关闭注册中心

任务相关类

 

JobCoreConfiguration：job核心配置

public final class JobCoreConfiguration {
    private final String jobName;               //job名称
    private final String cron;                  //cron表达式
    private final int shardingTotalCount;       //分片数
    private final String shardingItemParameters;//分片参数
    private final String jobParameter;          //任务参数
    private final boolean failover;             //是否开始任务失效转移
    private final boolean misfire;              //是否开启任务错过重新执行
    private final String description;
    private final JobProperties jobProperties;

    public static JobCoreConfiguration.Builder newBuilder(String jobName, String cron, int shardingTotalCount) {
        return new JobCoreConfiguration.Builder(jobName, cron, shardingTotalCount);
    }

    getter方法，没有setter方法
