本文详细介绍了Flowable中的部署类，包括EngineDeployment、Deployment、DeploymentEntity、AppDeployment及其实体类，讨论了它们在流程存储库中的角色，作为资源容器的功能，并提到了如何使用DeploymentBuilder进行部署操作。

Flowable源码地址：https://github.com/flowable/flowable-engine

EngineDeployment 引擎部署接口类

表示已存在于引擎存储库中的部署
部署是资源的容器，如流程定义、案例定义、图像、表单等

package org.flowable.common.engine.api.repository;

import java.util.Date;
import java.util.Map;

/**
 * @author Tijs Rademakers
 */
public interface EngineDeployment {

    String getId();

    String getName();

    Date getDeploymentTime();

    String getCategory();

    String getKey();
    
    String getDerivedFrom();

    String getDerivedFromRoot();

    String getTenantId();
    
    String getEngineVersion();
    
    boolean isNew();

    Map<String, EngineResource> getResources();
}

Deployment部署接口类

继承引擎部署接口类EngineDeployment
表示已存在于流程存储库中的部署
部署是资源的容器，如流程定义、案例定义、图像、表单等
当部署通过{@link org.flowable.engine.RuntimeService}“部署”时，流程引擎将识别某些此类资源类型并对其采取行动（例如流程定义）将被解析为可执行的Java组件）
要创建部署，请使用{@link org.flowable.engine.repository.DeploymentBuilder}。部署本身是一个只读对象，部署后其内容无法更改（因此需要使用的生成器）

package org.flowable.engine.repository;

import org.flowable.common.engine.api.repository.EngineDeployment;

/**
 * @author Tom Baeyens
 * @author Joram Barrez
 */
public interface Deployment extends EngineDeployment {

    String getParentDeploymentId();
}

DeploymentEntity 部署实体接口类

继承部署接口类Deployment

package org.flowable.engine.impl.persistence.entity;

import java.util.Date;
import java.util.List;
import java.util.Map;

import org.flowable.common.engine.api.repository.EngineResource;
import org.flowable.common.engine.impl.persistence.entity.Entity;
import org.flowable.engine.repository.Deployment;

/**
 * @author Tom Baeyens
 * @author Joram Barrez
 */
public interface DeploymentEntity extends Deployment, Entity {

    void addResource(ResourceEntity resource);

    void addDeployedArtifact(Object deployedArtifact);

    <T> List<T> getDeployedArtifacts(Class<T> clazz);

    void setName(String name);

    void setCategory(String category);

    void setKey(String key);

    void setTenantId(String tenantId);

    void setResources(Map<String, EngineResource> resources);

    void setDeploymentTime(Date deploymentTime);

    @Override
    boolean isNew();

    void setNew(boolean isNew);
    
    void setDerivedFrom(String derivedFrom);

    void setDerivedFromRoot(String derivedFromRoot);
    
    void setParentDeploymentId(String parentDeploymentId);

    void setEngineVersion(String engineVersion);

}

AppDeployment 应用部署接口

继承引擎部署接口类EngineDeployment

package org.flowable.app.api.repository;

import org.flowable.common.engine.api.repository.EngineDeployment;

public interface AppDeployment extends EngineDeployment{

}

AppDeploymentEntity 应用部署实体接口类

继承应用部署接口类AppDeployment

package org.flowable.app.engine.impl.persistence.entity;

import java.util.Date;
import java.util.List;
import java.util.Map;

import org.flowable.app.api.repository.AppDeployment;
import org.flowable.common.engine.api.repository.EngineResource;
import org.flowable.common.engine.impl.persistence.entity.Entity;

/**
 * @author Tijs Rademakers
 * @author Joram Barrez
 */
public interface AppDeploymentEntity extends AppDeployment, Entity {

    void addResource(AppResourceEntity resource);

    void addDeployedArtifact(Object deployedArtifact);

    <T> List<T> getDeployedArtifacts(Class<T> clazz);

    void setName(String name);

    void setCategory(String category);
    
    void setKey(String key);

    void setTenantId(String tenantId);

    void setResources(Map<String, EngineResource> resources);

    void setDeploymentTime(Date deploymentTime);

    @Override
    boolean isNew();

    void setNew(boolean isNew);
}
