当我在Spring中编写代码时,我总是使用注释,并且在基于xml的配置时总是卡住。现在,我遇到了一个可能非常简单的问题。如果你能帮助我,我会很感激。

编译代码中的IllegalAccessError
(不涉及反射)通常意味着版本不匹配:客户端代码是针对依赖版本编译的,其中成员具有更宽松的访问修饰符。更新您的Maven依赖项。
(因为这是一个非常古老的问题,最近出现了问题:所涉及的版本都已过时,应该升级到现代版本,这应该可以解决问题。)

!. 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"

</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;
