Spring整合MongoDB查询报错

Question

配置文件:

<!-- mongodb -->
<bean id="mongo" class="org.springframework.data.mongodb.core.MongoFactoryBean">
    <property name="host" value="${mongo.host}" />
    <property name="port" value="${mongo.port}" />
</bean>
<!--<mongo:mongo host="${mongo.host}" port="${mongo.port}"></mongo:mongo>-->
<mongo:db-factory mongo-ref="mongo" dbname="${mongo.databaseName}" />
<bean id="mongoTemplate" class="org.springframework.data.mongodb.core.MongoTemplate">
    <constructor-arg name="mongoDbFactory" ref="mongoDbFactory" />
</bean>
<mongo:repositories base-package="com.example

.repository.geo" />

代码:

/**

• 根据经纬度查找附近的地理位置

• @param lat

• 经度，如39.912232

• @param lng

• 维度 116.412323232

• @param maxDistance

• 距离目标点的最大距离 ，单位为角度， 建议 0.5~1.5，一个单位长度误差范围为111km

• @param maxCount

• 结果数目，建议 1~3

• @return maxDistance范围内的位置，由近到远排序
  */

1. List<GeoLocation> serarchNear(double lat, double lng, double maxDistance, int maxCount) {

      try {
          Point point = new Point(lng, lat);
          Query query = new Query(Criteria.where("loc").near(point).maxDistance(maxDistance));
          query.limit(maxCount);
   
          List<GeoLocation> find = template.find(query, GeoLocation.class);
   
          return find;
      } catch (Exception e) {
          return null;
      }
   

   }
