cvc-complex-type.2.4.c：匹配通配符是严格的，但找不到元素“mongo:mongo”的声明。 [11]

Question

我的 xml 仅适用于 spring-mongo.xsd 架构的 version 1.8。当我尝试使用latest（当前为3.0）时，我得到了这些错误：

cvc-complex-type.2.4.c: The matching wildcard is strict, but no declaration can be found for element 'mongo:mongo'. [11] 
cvc-complex-type.3.2.2: Attribute 'mongo-ref' is not allowed to appear in element 'mongo:db-factory'. [12] 
cvc-complex-type.3.2.2: Attribute 'username' is not allowed to appear in element 'mongo:db-factory'. [12] 
cvc-complex-type.3.2.2: Attribute 'password' is not allowed to appear in element 'mongo:db-factory'. [12] 

这是我的 xml：

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xmlns="http://www.springframework.org/schema/beans"
       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.xsd
       http://www.springframework.org/schema/data/mongo
       http://www.springframework.org/schema/data/mongo/spring-mongo.xsd">

    <mongo:mongo id="mongo" replica-set="${mongo.replicaset}" write-concern="${mongo.write_concern:REPLICAS_SAFE}"/>
    <mongo:db-factory id="DbFactory" mongo-ref="mongo" dbname="${mongo.db}" username="${mongo.username}" password="${mongo.password}"/>
    <bean id="mongoTemplate" class="org.springframework.data.mongodb.core.MongoTemplate">
        <constructor-arg ref="DbFactory"/>
        <property name="writeResultChecking" value="EXCEPTION"/>
    </bean>
</beans>

根据其他答案，我尝试将credentials 属性与连接字符串一起使用，但即使这样也被拒绝了？

Answer 1

您应该将 xsd 版本修复为匹配的 spring-data-mongo 版本。 （为了防止意外，而不是“依赖最新的”） 所以：

xsi:schemaLocation="...
   http://www.springframework.org/schema/data/mongo
   http://www.springframework.org/schema/data/mongo/spring-mongo.YOUR.VERSION.xsd">

要将您的 xml 升级到 3.0（当前最新）： See here

表 4. 删除的 XML 命名空间元素和属性：

Element Attribute	Replacement in 3.x	Comment
<mongo:db-factory mongo-ref="…​" />	<mongo:db-factory mongo-client-ref="…​" />	Referencing a com.mongodb.client.MongoClient.
<mongo:mongo-client credentials="…​" />	<mongo:mongo-client credential="…​" />	Single authentication data instead of list.
...	...	...

1. cvc-complex-type.2.4.c: The matching wildcard is strict, but no declaration can be found for element 'mongo:mongo'. [11] 
   

   使用mongo:mongo-client（从1.8更改为2.0）。

2. cvc-complex-type.3.2.2: Attribute 'mongo-ref' is not allowed to appear in element 'mongo:db-factory'. [12] 
   

   因此，将其替换为 mongo-client-ref（引用来自 1. 的客户端）。

3. cvc-complex-type.3.2.2: Attribute 'username' is not allowed to appear in element 'mongo:db-factory'. [12] 
   cvc-complex-type.3.2.2: Attribute 'password' is not allowed to appear in element 'mongo:db-factory'. [12] 
   

   您应该使用：mongo-client 的credential 属性。

请同时考虑表 3（writeConcern 现在具有不同的值）作为表 5（mongo-client-ref，connection-string）。

connection-string最好参考(current)Mongo DB Manual。

这是应用此答案后编辑的 xml，不确定它是否正确，但我没有收到 xml 验证错误：
