Connect and operate mongodb3.0 with spring

There's a record in front of it. Connect and manipulate the MongoDB database directly in Java code without using spring, followed by a record of using spring as a simple way to manipulate MongoDB in Java.
Maven Guide Package configuration:Because Sping and SPRINGMVC are involved, it is also necessary to import their related packages:

<project xmlns= "http://maven.apache.org/POM/4.0.0" xmlns:xsi= "Http://www.w3.org/2001/XMLSchema-instance" xsi: schemalocation= "http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd" > <modelversion >4.0.0</modelVersion> <groupId>spring_mongo</groupId> <artifactid>spring_mongo</ artifactid> <packaging>war</packaging> <version>0.0.1-SNAPSHOT</version> <name> Spring_mongo Maven webapp</name> <url>http://maven.apache.org</url> <dependencies> < Dependency> <groupId>org.springframework.data</groupId> <artifactid>spring-data-mongodb        </artifactId> <version>1.8.0.RELEASE</version> </dependency> <dependency> <groupId>org.mongodb</groupId> <artifactId>mongo-java-driver</artifactId> <vers Ion>3.0.3</version> </dependency> <dependEncy> <groupId>commons-logging</groupId> <artifactId>commons-logging</artifactId> <version>1.2</version> </dependency> <dependency> &LT;GROUPID&GT;ORG.SPRINGFR Amework</groupid> <artifactId>spring-test</artifactId> <version>4.1.6.release</ve rsion> </dependency> <dependency> <groupId>junit</groupId> &LT;ARTIFACTID&G        t;junit</artifactid> <version>4.11</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-context</artifactId> <v ersion>4.1.7.release</version> </dependency> <dependency> <groupid>org.springframe Work</groupid> <artifactId>spring-context-support</artifactId> <version>4.0.9.releas E</version> </dependency> </dependencies> <build> <plugins> <plugin> <artif Actid>maven-compiler-plugin</artifactid> <version>2.3.2</version> <c                    Onfiguration> <source>1.7</source> <target>1.7</target>                        <encoding>UTF-8</encoding> <compilerArguments> <verbose/> <bootclasspath>${java.home}/lib/rt.jar;${java.home}/lib/jce.jar</boot classpath> </compilerArguments> </configuration> </plug in> </plugins> <finalName>spring_mongo</finalName> </build></project>

Spring Base configuration:The main is to open the annotation scan, etc.:

<?xml version= "1.0" encoding= "UTF-8"? ><beans xmlns:task= "Http://www.springframework.org/schema/task" xmlns= "Http://www.springframework.org/schema/beans" xmlns:xsi= "Http://www.w3.org/2001/XMLSchema-instance" xmlns: context= "Http://www.springframework.org/schema/context" xsi:schemalocation= "http://www.springframework.org/ schema/beanshttp://www.springframework.org/schema/beans/spring-beans-3.0.xsdhttp://www.springframework.org/ schema/contexthttp://www.springframework.org/schema/context/spring-context-3.0.xsdhttp:// Www.springframework.org/schema/taskhttp://www.springframework.org/schema/task/spring-task-3.1.xsd "> <!-- Auto-scan (auto-inject)-<context:component-scan base-package= "spring_mogo.dao.daoImp"/> <!--importing MongoDB configuration Files--&G    T <import resource= "Spring-mongodb305.xml"/> <!--opening annotations--<context:annotation-config/></beans& Gt

spring connect MongoDB and establish the configuration of the associated factory:

<?xml version= "1.0" encoding= "UTF-8"? ><beans xmlns= "Http://www.springframework.org/schema/beans" xmlns: Xsi= "Http://www.w3.org/2001/XMLSchema-instance" xmlns:p= "http://www.springframework.org/schema/p" 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-3.0.xsd Http://www.springframe Work.org/schema/data/mongo http://www.springframework.org/schema/data/mongo/spring-mongo.xsd "> <!--SP Ring Connection MongoDB Database configuration--<mongo:mongo-client host= "192.168.0.201" port= "27017" credentials= "tuzongxun:[email& Nbsp;protected] "id=" MONGO "> <mongo:client-options write-concern=" SAFE "/> </mongo:mongo-client&gt     ;    <mongo:db-factory id= "Mongodbfactory" dbname= "mongotest" mongo-ref= "Mongo"/> <!--just use this call to the appropriate method-- <bean id= "Mongotemplate" class= "ORG.SPRINGFRAmework.data.mongodb.core.MongoTemplate "> <constructor-arg name=" mongodbfactory "ref=" Mongodbfactory "/> </bean> </beans>

entity classes corresponding to the database:It is important to note that there is a need to implement the serialized interface and set the UID properties, otherwise the database return result can not be converted to object properties directly in the operation:

Package Spring_mongo.models;import Java.io.serializable;public class Usermodel implements Serializable {    private Static final Long serialversionuid = 1L;    Private String userName;    private String password;    Public Usermodel (String userName, string password) {        super ();        This.username = UserName;        This.password = password;    }    Public String GetUserName () {        return userName;    }    public void Setusername (String userName) {        this.username = userName;    }    Public String GetPassword () {        return password;    }    public void SetPassword (String password) {        this.password = password;    }}

Get operations based on spring configuration MongoDB applicationcontextaware Interface:

Package Spring_mogo.dao.daoimp;import Org.springframework.beans.beansexception;import Org.springframework.context.applicationcontext;import Org.springframework.context.ApplicationContextAware; Import Org.springframework.data.mongodb.core.mongotemplate;public abstract class Abstractbasemongotemplete Implements        Applicationcontextaware {    protected mongotemplate mongotemplate;    /**     * @Description based on profile settings mongotemplate     * @param mongotemplate     *    /public void Setmongotemplate ( Mongotemplate mongotemplate) {        this.mongotemplate = mongotemplate;    }    @Override public    void Setapplicationcontext (ApplicationContext applicationcontext)            throws Beansexception {        Mongotemplate mongotemplate = Applicationcontext.getbean (                "Mongotemplate", mongotemplate.class);        Setmongotemplate (mongotemplate);    }}

The interface of the operational database and the corresponding implementation class:Demonstrates the most basic additions and deletions, which need to be noted in the Declaration of parameters and the conversion of the entity class when the return data is received: (1) interface:

Package Spring_mogo.dao;import Java.util.list;import Spring_mongo.models.usermodel;public interface UserDao {/** * Query data * * @author: Tuzongxun * @Title: FINDALL * @param @return * @return list<usermodel> *    @date May 3:07:39 PM * @throws */public list<usermodel> findAll (); /** * Added Data * * @author: Tuzongxun * @Title: Insertuser * @param @param user * @return void * @    Date May: 3:09:45 PM * @throws */public void Insertuser (Usermodel user);     /** * Delete Data * * @author: Tuzongxun * @Title: Removeuser * @param @param userName * @return void    * @date May 3:09:55 PM * @throws */public void Removeuser (String userName); /** * Modify Data * * @author: Tuzongxun * @Title: UpdateUser * @param @param user * @return void * @    Date May: 3:10:06 PM * @throws */public void UpdateUser (Usermodel user);/** * Search by condition * * @author: Tuzongxun * @Title: Findforrequery * @param * @return void * @date Ma Y, 3:23:37 PM * @throws * * Public list<usermodel> findforrequery (String userName);

(2) Implementation class, here to inheritAbstractbasemongotemplete class to obtain mongotemplete for various operations:

Package Spring_mogo.dao.daoimp;import Java.util.list;import Org.springframework.data.mongodb.core.query.Criteria; Import Org.springframework.data.mongodb.core.query.query;import Org.springframework.data.mongodb.core.query.update;import Org.springframework.stereotype.component;import Spring _mogo.dao.userdao;import Spring_mongo.models.usermodel;import Com.mongodb.basicdbobject;import Com.mongodb.DBObject, @Component ("Userdaoimp") public class Userdaoimp extends Abstractbasemongotemplete implements Userdao {/** * query all data * * @author: Tuzongxun * @Title: FindAll * @Description: TODO * @param @        return * @date May 3:10:29 PM * @throws */@Override public list<usermodel> findAll () {                The collection corresponding to the Corpse class and the corresponding set name, so that the query results directly mapped list<usermodel> userlist = Mongotemplate.findall (Usermodel.class,        "User");    return userlist; }/** * Added data * * @author: Tuzongxun * @Title: Insertuser * @DescrIption:todo * @param @param user * @date May 3:10:45 PM * @throws */@Override public void        Insertuser (Usermodel user) {//sets the document object that needs to be inserted into the database DBObject objects = new Basicdbobject ();        Object.put ("UserName", User.getusername ());        Object.put ("Password", User.getpassword ());    Mongotemplate.insert (object, "user"); /** * Delete Data conditionally * * @author: Tuzongxun * @Title: Removeuser * @Description: TODO * @param @para M UserName * @date May 3:11:01 PM * @throws */@Override public void Removeuser (String userName        {//Set the delete condition, if the condition content is empty, delete all query query = new query ();        criteria = new Criteria ("UserName");        Criteria.is (UserName);        Query.addcriteria (criteria);    Mongotemplate.remove (query, "user"); }/** * Modify Data * * @author: Tuzongxun * @Title: UpdateUser * @Description: TODO * @param @param u Ser * @date May 13, 2016 3:11:12 PM * @throws */@Override public void UpdateUser (Usermodel user) {//Set Modify condition Query        query = new query ();        criteria = new Criteria ("UserName");        Criteria.is (User.getusername ());        Query.addcriteria (criteria);        Set Modify Update update = update.update ("Password", User.getpassword ());    Parameters: Query condition, change result, set name Mongotemplate.updatefirst (query, update, "user"); /** * Search by condition * * @author: Tuzongxun * @Title: Findforrequery * @Description: TODO * @param @p Aram UserName * @date May, 4:08:15 PM * @throws */@Override public list<usermodel> FINDFO        Rrequery (String userName) {query query = new query ();        criteria = new Criteria ("UserName");        Criteria.is (UserName);        Query.addcriteria (criteria); Query condition, collection corresponding entity class, collection name list<usermodel> userlist = mongotemplate.find (query, Usermodel.class, "uSer ");    return userlist; }}

Test class:To verify the correctness of the above code and configuration, the test class code is as follows:

Package Spring_mongo.test;import Java.util.list;import Org.junit.test;import org.junit.runner.runwith;import Org.springframework.beans.factory.annotation.autowired;import Org.springframework.test.context.contextconfiguration;import Org.springframework.test.context.junit4.springjunit4classrunner;import Spring_mogo.dao.userdao;import Spring_ Mongo.models.UserModel; @RunWith (Springjunit4classrunner.class) @ContextConfiguration (locations = {"Classpath:    Spring.xml "}) public class Mongotest {@Autowired private Userdao Userdao; /** * Query Test * * @author: Tuzongxun * @Title: Monfindtest * @param * @return void * @date May 13 , 3:27:51 PM * @throws */@Test public void Monfindtest () {List<usermodel> usermodels = u        Serdao.findall ();                if (usermodels! = null && usermodels.size () > 0) {for (Usermodel user:usermodels) { System.out.println (User.getusername () + ":" + user.
