这是 Mongo 驱动程序中的错误还是我做错了什么？

获取以下异常:

Caused by: org.springframework.beans.ConversionNotSupportedException: Failed to convert property value of type 'java.lang.String' to required type 'com.mongodb.ServerAddress[]' for property 'replicaSetSeeds'; nested exception is java.lang.IllegalStateException: Cannot convert value of type [java.lang.String] to required type [com.mongodb.ServerAddress] for property 'replicaSetSeeds[0]': no matching editors or conversion strategy found

下面是我的spring配置

 <bean id="defaultMongoTypeMapper"  class="org.springframework.data.mongodb.core.convert.DefaultMongoTypeMapper">
    <constructor-arg name="typeKey"><null/></constructor-arg>
 </bean>

 <bean id="mappingMongoConverter" class="org.springframework.data.mongodb.core.convert.MappingMongoConverter">
    <constructor-arg name="mongoDbFactory" ref="mongoDbFactory" />
    <constructor-arg name="mappingContext" ref="mappingContext" />
    <property name="typeMapper" ref="defaultMongoTypeMapper" />
 </bean>

 <bean id="mongoTemplate" class="org.springframework.data.mongodb.core.MongoTemplate">
    <constructor-arg name="mongoDbFactory" ref="mongoDbFactory" />
    <constructor-arg name="mongoConverter" ref="mappingMongoConverter" />   
    <property name="writeConcern">
        <util:constant static-field="com.mongodb.WriteConcern.SAFE" ></util:constant>
    </property>
 </bean>

使用的 jar /驱动程序:
spring-beans-3.2.0.RELEASE.jar mongo-java-driver-2.11.3.jar

使用以下代码修复它:

<bean id="mongoClient" class="com.mongodb.MongoClient">
    <constructor-arg>
        <list>
            <value>161.141.16.100:27017</value>
            <value>161.141.16.101:27017</value>
        </list>
    </constructor-arg>
</bean>

<mongo:db-factory id="mongoDbFactory" dbname="test" mongo-ref="mongoClient"/>

最佳答案

你可能正在使用

<property name="[variable]" ref="[bean]"/>

代替

<property name="[variable]" value="[bean]"/>

ref 引用一个 spring bean，value 转换为字符串。

关于java - 无法将类型 'java.lang.String' 的属性值转换为属性 'com.mongodb.ServerAddress[]' 所需的类型 'replicaSetSeeds'，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/19429137/
