Spring/MavenでMongoDBを設定するのに手助けが必要

Question

私はSpringでコードを作成するときに常に注釈を使用し、XMLベースの設定に関しては常に固執します。今、私はおそらく非常に簡単な問題で立ち往生しています。あなたが私にこれを手伝ってもらえたら嬉しいです。

Answer 1

IllegalAccessErrorコンパイル済みコード（リフレクションは含まない）は、通常、バージョンが不一致であることを意味します。クライアントコードは、メンバーがより許容的なアクセス修飾子を持つバージョンの依存ファイルに対してコンパイルされました。 Mavenの依存関係を更新してください。

（これは最近ぶつかってしまった非常に古い質問ですので：関与バージョンはすべて廃止され、問題を解決する必要があり、現代のバージョンにアップグレードする必要があります）

Answer 2

!. Changes in Xml 

    spring-servlet.xml you can also change name with spring-servlet.xml to yourProjectName-servlet.xml 

     http://www.springframework.org/schema/data/mongo 
      http://www.springframework.org/schema/data/mongo/spring-mongo-1.0.xsd 

      change to 1.1 

        http://www.springframework.org/schema/data/mongo 
     http://www.springframework.org/schema/data/mongo/spring-mongo-1.1.xsd 



    <mongo:mongo host="localhost" port="27017"> 

    <mongo:options connections-per-host="100" 
    threads-allowed-to-block-for-connection-multiplier="5" 
      max-wait-time="120000000" 
      connect-timeout="10000000" 
      socket-keep-alive="true" 
      socket-timeout="15000000" 
      auto-connect-retry="true"/> 

    </mongo:mongo> 


    <mongo:db-factory dbname="jobstix" 
     mongo-ref="mongo" /> 
    <bean id="mongoTypeMapper" 
     class="org.springframework.data.mongodb.core.convert.DefaultMongoTypeMapper"> 
     <constructor-arg name="typeKey"> 
      <null /> 
     </constructor-arg> 
    </bean> 
    <bean id="mongoMappingContext" 
     class="org.springframework.data.mongodb.core.mapping.MongoMappingContext" /> 
    <bean id="mongoConverter" 
     class="org.springframework.data.mongodb.core.convert.MappingMongoConverter"> 
     <constructor-arg name="mongoDbFactory" ref="mongoDbFactory" /> 
     <constructor-arg name="mappingContext" ref="mongoMappingContext" /> 
     <property name="typeMapper" ref="mongoTypeMapper"></property> 
    </bean> 
    <bean id="mongoTemplate" class="org.springframework.data.mongodb.core.MongoTemplate"> 
     <constructor-arg name="mongoDbFactory" ref="mongoDbFactory" /> 
     <constructor-arg name="mongoConverter" ref="mongoConverter" /> 
     <property name="writeResultChecking" value="EXCEPTION" /> 
    </bean> 

2. Put Four Jars OR Get From Maven 

/Test/WebContent/WEB-INF/lib/mongo-java-driver-2.10.1.jar 
/Test/WebContent/WEB-INF/lib/spring-data-commons-1.5.1.RELEASE.jar 
/Test/WebContent/WEB-INF/lib/spring-data-commons-core-1.3.1.RELEASE.jar 
/Test/WebContent/WEB-INF/lib/spring-data-mongodb-1.3.1.RELEASE.jar 

3. In Dao/Service/Controller you can call these connection to Autowired 

    @Autowired 
    private MongoTemplate mongoTemplate; 

    @Autowired 
    private MongoOperations mongoOperation;
