示例应用程序简介（MongoShop产品目录）

在学习完本教程之后，将构建具有以下功能要求的示例应用程序（MongoShop产品目录）：

1.搜索具有不同条件的产品（例如，sku，产品类型，标题，stc）

2.创建具有不同类别的新产品。

3.编辑选定的产品详细信息

4.从查询屏幕删除选定的产品。

表示层：

JSF在此示例应用程序中用作表示层技术。 PrimeFaces是用于增强JSF UI的轻量级组件之一。 前端交互由该层中的JSF支持bean控制。

服务层：

使用Spring管理的单例服务对象。 业务服务和应用程序逻辑编写在此层中

数据层：

使用Spring数据MongoDB组件。 它提供了与MongoDB面向文档的数据库的集成。 它提供了MongoTemplate，以便可以轻松执行MongoDB操作。 而且，Spring存储库样式数据访问层可以使用Spring数据MongoDB轻松编写。

MongoDB模式设计和数据准备

MongoDB简介

MongoDB是一个开源可扩展的高性能NoSQL数据库。 它是一个面向文档的存储。 它可以存储具有动态模式的JSON样式的文档。 在此应用程序中，每个产品都以JSON样式的文档存储在MongoDB中。

MongoDB中的架构设计

目录中的每个产品均包含常规产品信息（例如，sku，标题和产品类型），价格详细信息（例如，零售价格和标价）和产品子详细信息（例如，音频CD的曲目/书籍的章节）。 在此应用程序中，使用MongoDB。 模式设计将更侧重于数据使用。 它与传统的RDBMS模式设计不同。 MongoDB中的架构设计应为：

样本数据：

x= {sku: '1000001',type: 'Audio Album',title: 'A Love Supreme',description: 'by John Coltrane',publisher: 'Sony Music',pricing: {list: 1200,retail: 1100},details: {title: 'A Love Supreme [Original Recording Reissued]',artist: 'John Coltrane',genre:  'Jazz' ,tracks: ['A Love Supreme Part I: Acknowledgement','A Love Supreme Part II - Resolution','A Love Supreme, Part III: Pursuance','A Love Supreme, Part IV-Psalm'],}
}y= {sku: '1000002',type: 'Audio Album',title: 'Love Song',description: 'by Khali Fong',publisher: 'Sony Music',pricing: {list: 1000,retail: 1200},details: {title: 'Long Song [Original Recording Reissued]',artist: 'Khali Fong',genre:  'R&B',tracks: ['Love Song','Spring Wind Blow','Red Bean','SingAlongSong'],}
}z= {sku: '1000003',type: 'Book',title: 'Node.js for PHP Developers',description: 'by Owen Peter',publisher: 'OReilly Media',pricing: {list: 2500,retail: 2100},details: {title: 'Node.js for PHP Developers',author: 'Mark Owen',genre:  'Technology',chapters: ['Introduction to Node','Server-side JS','PHP API','Example'],}
}

示例查询以添加数据：

db.product.save(x);
db.product.save(y);
db.product.save(z);

示例查询以测试示例数据：

db.product.find({'sku':'1000004'});
db.product.find({'type':'Audio Album'});
db.product.find({'type':'Audio Album', 'details.genre': 'Jazz'});

我的脸

MyFaces用作此应用程序中的JSF实现。 以下详细信息应添加到web.xml中

PrimeFaces主题

如前所述，PrimeFaces库用于增强UI。 该库几乎不需要配置。 PrimeFaces为您的Web应用程序提供了许多预先设计的主题。 在本例中，我们使用“蓝天”主题。 我们只是在web.xml中添加以下设置

<context-param><param-name>primefaces.THEME</param-name><param-value>glass-x</param-value></context-param>

JSF和Spring集成：

要将JSF与Spring集成，必须在Faces-config.xml中指定SpringBeanFacesELResolver

Faces-config.xml

<?xml version='1.0' encoding='UTF-8'?>
<faces-config version='2.0' xmlns='http://java.sun.com/xml/ns/javaee'xmlns:xi='http://www.w3.org/2001/XInclude'xmlns:xsi='http://www.w3.org/2001/XMLSchema-instance' xsi:schemaLocation='http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-facesconfig_2_0.xsd'><application><el-resolver>org.springframework.web.jsf.el.SpringBeanFacesELResolver</el-resolver></application><factory><partial-view-context-factory>org.primefaces.context.PrimePartialViewContextFactory</partial-view-context-factory></factory>

MongoDB连接详细信息

为了连接到MongoDB，您必须以XML注册MongoDbFactory实例。 连接详细信息在spring-application-context.xml中指定

使用Spring Data Repository和MongoTemplate来查询数据

Spring资料储存库：

Spring数据存储库抽象减少了用于编写应用程序数据访问层的样板代码。 Repository接口的自动实现提供了对mongoDB的简单操作。 它有助于我们的产品保存和删除功能，使

MongoTemplate：

MongoTemplate提供了方便的操作来创建，更新，删除和查询MongoDB文档，并提供了域对象和MongoDB文档之间的映射。 在我们的应用程序中，由于spring数据存储库无法满足搜索功能的要求，因此我们使用MongoTemplate来归档搜索功能。

自定义Spring数据存储库：

由于无法通过Spring数据存储库抽象轻松地实现产品搜索，因此我们想使用MongoDBTemplate实现多级Criteira产品搜索。 为了使用MongoTemplate丰富Spring数据存储库，我们可以执行以下操作来定制存储库：

ProductRepository.java

package com.borislam.repository;import java.util.List;
import org.springframework.data.repository.PagingAndSortingRepository;
import com.borislam.domain.Product;public interface ProductRepository  extends PagingAndSortingRepository<Product, String> , ProductRepostitoryCustom{List<product> findByType(String type);List<product> findByTypeAndTitle(String type, String title); Product findBySku(String sku);
}

ProductRepositoryCustom.java

package com.borislam.repository;import java.util.List;
import com.borislam.domain.Product;
import com.borislam.view.ProductSearchCriteria;public interface ProductRepostitoryCustom {public List<product> searchByCriteria(ProductSearchCriteria criteria);}

ProductRepositoryImpl.java

package com.borislam.repository.impl;import java.util.List;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.data.mongodb.core.MongoTemplate;
import org.springframework.data.mongodb.core.query.Criteria;
import org.springframework.data.mongodb.core.query.Query;
import org.springframework.util.StringUtils;
import com.borislam.domain.Product;
import com.borislam.repository.ProductRepostitoryCustom;
import com.borislam.view.ProductSearchCriteria;public class ProductRepositoryImpl implements ProductRepostitoryCustom{@Autowiredprivate MongoTemplate mongoTemplate;@Overridepublic List<product> searchByCriteria(ProductSearchCriteria criteria) {Query query = new Query();if ( StringUtils.hasText(criteria.getSku())) { Criteria c = Criteria.where('sku').is(criteria.getSku());query.addCriteria(c);}if (StringUtils.hasText(criteria.getTitle())) {Criteria c = Criteria.where('title').regex('.*' + criteria.getTitle() + '.*', 'i');query.addCriteria(c);}if (StringUtils.hasText(criteria.getDescription())) {Criteria c = Criteria.where('description').regex('.*' + criteria.getDescription() + '.*', 'i');query.addCriteria(c);}if (StringUtils.hasText(criteria.getProductType())) {Criteria c = Criteria.where('type').is(criteria.getProductType());query.addCriteria(c);}  if (StringUtils.hasText(criteria.getTrack())) {Criteria c = Criteria.where('details.tracks').regex('.*' + criteria.getTrack() + '.*', 'i');query.addCriteria(c);}if (StringUtils.hasText(criteria.getChapter())) {Criteria c = Criteria.where('details.chapters').regex('.*' + criteria.getChapter() + '.*', 'i');query.addCriteria(c);}return mongoTemplate.find(query, Product.class);}}

使用Spring数据存储库创建，编辑和删除数据

在本教程的最后一部分，我们将向MongoShop产品目录应用程序添加创建，编辑和删除功能。 搜索页面已修改。 在实际删除产品之前，已添加模式确认对话框

更新了search.xhtml

结论：

1. Spring Data Mongo DB提供了MongoTemplate，可让您轻松执行MongoDB操作。

2.借助Spring Data MongoDB，可以轻松将MongoDB JSON样式的文档映射到POJO

3. Spring数据的存储库抽象减少了访问MongoDB的样板代码。

4.您将自定义行为添加到spring数据存储库。

• 获取源代码

参考： 示例应用程序简介（MongoShop产品目录） ， MongoDB模式设计和数据准备 ， JSF（PrimeFaces）和Spring数据MongoDB集成 ， 带有Spring数据存储库和mongotemplate的Enquriy数据 ， 创建，编辑和删除数据 （来自我们的JCG合作伙伴 Boris）在“ Programming Peaceally和平”博客上，Lam表示。
