Spring Data，MongoDB和JSF集成教程

發布時間：2023/12/3 javascript 35 豆豆

生活随笔收集整理的這篇文章主要介紹了 Spring Data，MongoDB和JSF集成教程小編覺得挺不錯的,現在分享給大家,幫大家做個參考.

示例應用程序簡介（MongoShop產品目錄）

在學習完本教程之后，將構建具有以下功能要求的示例應用程序（MongoShop產品目錄）：

1.搜索具有不同條件的產品（例如，sku，產品類型，標題，stc）

2.創建具有不同類別的新產品。

3.編輯選定的產品詳細信息

4.從查詢屏幕刪除選定的產品。

表示層：

JSF在此示例應用程序中用作表示層技術。 PrimeFaces是用于增強JSF UI的輕量級組件之一。前端交互由該層中的JSF支持bean控制。

服務層：

使用Spring管理的單例服務對象。業務服務和應用程序邏輯編寫在此層中

數據層：

使用Spring數據MongoDB組件。它提供了與MongoDB面向文檔的數據庫的集成。它提供了MongoTemplate，以便可以輕松執行MongoDB操作。而且，Spring存儲庫樣式數據訪問層可以使用Spring數據MongoDB輕松編寫。

MongoDB模式設計和數據準備

MongoDB簡介

MongoDB是一個開源可擴展的高性能NoSQL數據庫。它是一個面向文檔的存儲。它可以存儲具有動態模式的JSON樣式的文檔。在此應用程序中，每個產品都以JSON樣式的文檔存儲在MongoDB中。

MongoDB中的架構設計

目錄中的每個產品均包含常規產品信息（例如，sku，標題和產品類型），價格詳細信息（例如，零售價格和標價）和產品子詳細信息（例如，音頻CD的曲目/書籍的章節）。在此應用程序中，使用MongoDB。模式設計將更側重于數據使用。它與傳統的RDBMS模式設計不同。 MongoDB中的架構設計應為：

樣本數據：

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'],} }

示例查詢以添加數據：

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

示例查詢以測試示例數據：

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

我的臉

MyFaces用作此應用程序中的JSF實現。以下詳細信息應添加到web.xml中

PrimeFaces主題

如前所述，PrimeFaces庫用于增強UI。該庫幾乎不需要配置。 PrimeFaces為您的Web應用程序提供了許多預先設計的主題。在本例中，我們使用“藍天”主題。我們只是在web.xml中添加以下設置

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

JSF和Spring集成：

要將JSF與Spring集成，必須在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> </faces-config>

完整的web.xml

<?xml version='1.0' encoding='UTF-8'?> <web-app id='WebApp_ID' version='3.0'xmlns='http://java.sun.com/xml/ns/javaee'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-app_3_0.xsd'><context-param><param-name>contextConfigLocation</param-name><param-value>WEB-INF/spring-application-context.xml</param-value></context-param><context-param><param-name>errorPageUrl</param-name><param-value>/pages/systemError.do</param-value></context-param><context-param><param-name>facelets.DEVELOPMENT</param-name><param-value>false</param-value></context-param><context-param><param-name>facelets.REFRESH_PERIOD</param-name><param-value>2</param-value></context-param><context-param><param-name>javax.faces.STATE_SAVING_METHOD</param-name><param-value>client</param-value></context-param><context-param><param-name>javax.servlet.jsp.jstl.fmt.localizationContext</param-name><param-value>resources.application</param-value></context-param><context-param><param-name>org.apache.myfaces.ALLOW_JAVASCRIPT</param-name><param-value>true</param-value></context-param><context-param><param-name>org.apache.myfaces.AUTO_SCROLL</param-name><param-value>false</param-value></context-param><context-param><param-name>org.apache.myfaces.DETECT_JAVASCRIPT</param-name><param-value>false</param-value></context-param><context-param><param-name>org.apache.myfaces.ERROR_HANDLING</param-name><param-value>false</param-value></context-param><context-param><param-name>org.apache.myfaces.EXPRESSION_FACTORY</param-name><param-value>org.jboss.el.ExpressionFactoryImpl</param-value></context-param><context-param><param-name>org.apache.myfaces.PRETTY_HTML</param-name><param-value>false</param-value></context-param><context-param><param-name>primefaces.THEME</param-name><param-value>glass-x</param-value></context-param> <servlet><servlet-name>Faces Servlet</servlet-name><servlet-class>org.apache.myfaces.webapp.MyFacesServlet</servlet-class><load-on-startup>1</load-on-startup></servlet><servlet-mapping><servlet-name>Faces Servlet</servlet-name><url-pattern>*.jsf</url-pattern></servlet-mapping><listener><listener-class>org.apache.myfaces.webapp.StartupServletContextListener</listener-class></listener><listener><listener-class>org.springframework.web.context.ContextLoaderListener</listener-class></listener> </web-app>

MongoDB連接詳細信息

為了連接到MongoDB，您必須以XML注冊MongoDbFactory實例。連接詳細信息在spring-application-context.xml中指定

spring-application-context.xml

<?xml version='1.0' encoding='UTF-8'?> <beans xmlns='http://www.springframework.org/schema/beans' xmlns:context='http://www.springframework.org/schema/context'xmlns:xsi='http://www.w3.org/2001/XMLSchema-instance'xmlns:util='http://www.springframework.org/schema/util'xmlns:mongo='http://www.springframework.org/schema/data/mongo'xsi:schemaLocation='http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.2.xsdhttp://www.springframework.org/schema/data/mongohttp://www.springframework.org/schema/data/mongo/spring-mongo.xsd http://www.springframework.org/schema/data/repositoryhttp://www.springframework.org/schema/data/repository/spring-repository.xsd http://www.springframework.org/schema/contexthttp://www.springframework.org/schema/context/spring-context-3.2.xsdhttp://www.springframework.org/schema/util http://www.springframework.org/schema/util/spring-util-3.2.xsd'><context:annotation-config/><context:component-scan base-package='com.borislam'/><mongo:mongo host='localhost' port='27017'> <mongo:optionsconnections-per-host='5' connect-timeout='30000'max-wait-time='10000' write-number='1'write-timeout='0'write-fsync='true'/></mongo:mongo><mongo:db-factory dbname='test' mongo-ref='mongo'/><mongo:repositories base-package='com.borislam.repository' /><bean id='mongoTemplate' class='org.springframework.data.mongodb.core.MongoTemplate'><constructor-arg ref='mongo'/><constructor-arg name='databaseName' value='test'/></bean> </beans>

使用Spring Data Repository和MongoTemplate來查詢數據

Spring資料儲存庫：

Spring數據存儲庫抽象減少了用于編寫應用程序數據訪問層的樣板代碼。 Repository接口的自動實現提供了對mongoDB的簡單操作。它有助于我們的產品保存和刪除功能，使

MongoTemplate：

MongoTemplate提供了方便的操作來創建，更新，刪除和查詢MongoDB文檔，并提供了域對象和MongoDB文檔之間的映射。在我們的應用程序中，由于spring數據存儲庫無法滿足搜索功能的要求，因此我們使用MongoTemplate來歸檔搜索功能。

自定義Spring數據存儲庫：

由于無法通過Spring數據存儲庫抽象輕松地實現產品搜索，因此我們想使用MongoDBTemplate實現多級Criteira產品搜索。為了使用MongoTemplate豐富Spring數據存儲庫，我們可以執行以下操作來定制存儲庫：

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);}}

Detail.java

package com.borislam.domain;import java.util.List;public class Detail {private String id;private String title;private String author;private String artist;private String genre;private List<string> pic;private List<string> chapters;private List<string> tracks;public String getTitle() {return title;}public void setTitle(String title) {this.title = title;}public String getAuthor() {return author;}public void setAuthor(String author) {this.author = author;}public String getGenre() {return genre;}public void setGenre(String genre) {this.genre = genre;}public List<string> getPic() {return pic;}public void setPic(List<string> pic) {this.pic = pic;}public List<string> getChapters() {return chapters;}public void setChapters(List<string> chapters) {this.chapters = chapters;}public String getId() {return id;}public void setId(String id) {this.id = id;}public String getArtist() {return artist;}public void setArtist(String artist) {this.artist = artist;}public List<string> getTracks() {return tracks;}public void setTracks(List<string> tracks) {this.tracks = tracks;}}

使用Spring數據存儲庫創建，編輯和刪除數據

在本教程的最后一部分，我們將向MongoShop產品目錄應用程序添加創建，編輯和刪除功能。搜索頁面已修改。在實際刪除產品之前，已添加模式確認對話框

更新了search.xhtml

ProductDetailsBean.java

更新了ProductService.java

package com.borislam.service;import java.util.List;import org.springframework.beans.factory.annotation.Autowired; import org.springframework.stereotype.Service;import com.borislam.domain.Product; import com.borislam.repository.ProductRepository; import com.borislam.view.ProductSearchCriteria;@Service public class ProductService {@Autowiredprivate ProductRepository productRepository;public List<Product> searchByCriteria(ProductSearchCriteria criteria){return productRepository.searchByCriteria(criteria);}public Product getProduct(String sku) {return productRepository.findBySku(sku);}public void saveProduct(Product p){ productRepository.save(p);}public void deleteProduct(Product p){ productRepository.delete(p);}}

結論：

1. Spring Data Mongo DB提供了MongoTemplate，可讓您輕松執行MongoDB操作。

2.借助Spring Data MongoDB，可以輕松將MongoDB JSON樣式的文檔映射到POJO

3. Spring數據的存儲庫抽象減少了訪問MongoDB的樣板代碼。

4.您將自定義行為添加到spring數據存儲庫。

獲取源代碼

參考：示例應用程序簡介（MongoShop產品目錄）， MongoDB模式設計和數據準備， JSF（PrimeFaces）和Spring數據MongoDB集成，帶有Spring數據存儲庫和mongotemplate的Enquriy數據，創建，編輯和刪除數據（來自我們的JCG合作伙伴 Boris）在“ Programming Peaceally和平”博客上，Lam表示。
