<bean id="mongoClient" class="org.springframework.data.mongodb.core.MongoClientFactoryBean">
    <property name="host" value="localhost" />
    <property name="port" value="27017" />
</bean>

<bean id="mongoTemplate" class="org.springframework.data.mongodb.core.MongoTemplate">
    <constructor-arg ref="mongoClient" />
    <constructor-arg name="databaseName" value="your_database_name" />
</bean>

@Autowired
private MongoTemplate mongoTemplate;

public void updateDocuments() {
    Query query = new Query(Criteria.where("field1").is("value1")); // 设置查询条件
    Update update = new Update().set("field2", "new_value"); // 设置更新内容

    mongoTemplate.updateMulti(query, update, YourEntityClass.class); // 更新满足条件的多个文档
}
