J2EE之wildfly 实践8 -- 集成NoSql(mongodb)

实践背景:在wildfly中使用hibernate-ogm框架操作mongodb数据库

条件:　　

• hibernate-ogm-wildfly10-module.zip：https://pan.baidu.com/s/1kVE1Rvh 密码：d2hl
• 安装mongodb数据库，网上自搜索教程。

步骤:

1. 　　将hibernate-ogm-wildfly10-module.zip解压到 WILDFLY10_HOME/modules中，产生WILDFLY10_HOME/modules/org文件夹。
2. 　　添加一个ExampleDS数据源，可随意创建，修改standalone.xml，在datasources节点下创建，代码如下:

   <datasource jta="true" jndi-name="java:/ExampleDS" pool-name="ExampleDS" enabled="true" use-ccm="true">
                       <connection-url>null</connection-url>
                       <driver-class>org.h2.Driver</driver-class>
                       <driver>h2</driver>
                       <security>
                           <user-name>sa</user-name>
                           <password>sa</password>
                       </security>
                   </datasource>

    

3.    修改默认绑定的数据源为ExampleDS，即在standalone.xml中的<subsystem xmlns="urn:jboss:domain:ee:4.0">节点下修改代码:

   <default-bindings context-service="java:jboss/ee/concurrency/context/default" datasource="java:/ExampleDS" managed-executor-service="java:jboss/ee/concurrency/executor/default" managed-scheduled-executor-service="java:jboss/ee/concurrency/scheduler/default" managed-thread-factory="java:jboss/ee/concurrency/factory/default"/>

   注:此时即可启动服务，服务已支持hibernate-ogm模块.

4. 创建实体类，代码如下:

   package com.sj.mrics.db.model;
   
   import java.io.Serializable;
   
   import java.util.Date;
   
   import javax.persistence.Entity;
   import javax.persistence.GeneratedValue;
   import javax.persistence.GenerationType;
   import javax.persistence.Id;
   import javax.persistence.Table;
   import javax.persistence.Temporal;
   import javax.persistence.TemporalType;
   
   
   import org.hibernate.annotations.Type;
   
   import com.fasterxml.jackson.databind.annotation.JsonSerialize;
   import com.sj.mrics.util.JsonDateSerializer;
   
   
   @Entity
   @Table(name = "weblog")
   public class WebLog implements Serializable{
       /**
        * weblog即为数据库中的collection名称
        */
       private static final long serialVersionUID = -914369413813954644L;
       @Id
       @GeneratedValue(strategy = GenerationType.IDENTITY)
       @Type(type = "objectid")
       private String id;
       private String msg;
       private String level;
       @JsonSerialize(using=JsonDateSerializer.class)
       private Date uptime;
       public String getId() {
           return id;
       }
       public void setId(String id) {
           this.id = id;
       }
       public String getMsg() {
           return msg;
       }
       public void setMsg(String msg) {
           this.msg = msg;
       }
       public String getLevel() {
           return level;
       }
       public void setLevel(String level) {
           this.level = level;
       }
       
       
       
       @Temporal(TemporalType.TIMESTAMP)
       public Date getUptime() {
           return uptime;
       }
       public void setUptime(Date uptime) {
           this.uptime = uptime;
       }
   }
