Question

我以下面的方式创建了收藏集</ p>

@Document(collection = "User")
public class User extends AbstractEntity{
    private static final long serialVersionUID = 1L;

    @NonNull
    private String deviceId;

    private GeoJsonPoint location;

    public String getDeviceId() {
        return deviceId;
    }

    public void setDeviceId(String deviceId) {
        this.deviceId = deviceId;
    }

    public GeoJsonPoint getLocation() {
        return location;
    }

    public void setLocation(GeoJsonPoint location) {
        this.location = location;
    }
}

和存储库如下

public interface UserRepository extends MongoRepository<User, String> {
    List<User> findAll();
    User insert(User u);
}

当我添加具有以下位置的新用户时

        User user1 = new User();
        user1.setDeviceId("1010101010");
        GeoJsonPoint locationPoint = new 
                     GeoJsonPoint(53.10, 75.10);
          user1.setLocation(locationPoint);
        //user1.setLocation();
        userRepository.save(user1);

Spring给出如下异常

原因： org.springframework.core.convert.ConverterNotFoundException：没有找到能够将[org.springframework.data.mongodb.core.geo.GeoJsonPoint]类型转换为[org.bson.Document]类型的转换器在org.springframework.core.convert.support.GenericConversionService.handleConverterNotFound（GenericConversionService.java:321）在org.springframework.core.convert.support.GenericConversionService.convert（GenericConversionService.java:194）在org.springframework.core.convert.support.GenericConversionService.convert（GenericConversionService.java:174）在org.springframework.data.mongodb.core.convert.MappingMongoConverter.getPotentiallyConvertedSimpleWrite（MappingMongoConverter.java:849）处在org.springframework.data.mongodb.core.convert.MappingMongoConverter.writeSimpleInternal（MappingMongoConverter.java:829）在org.springframework.data.mongodb.core.convert.MappingMongoConverter.writeProperties（MappingMongoConverter.java:488）在org.springframework.data.mongodb.core.convert.MappingMongoConverter.writeInternal（MappingMongoConverter.java:462）在org.springframework.data.mongodb.core.convert.MappingMongoConverter.writeInternal（MappingMongoConverter.java:436）在org.springframework.data.mongodb.core.convert.MappingMongoConverter.write（MappingMongoConverter.java:391）在org.springframework.data.mongodb.core.convert.MappingMongoConverter.write（MappingMongoConverter.java:86）在org.springframework.data.mongodb.core.MongoTemplate.toDocument（MongoTemplate.java:1070）在org.springframework.data.mongodb.core.MongoTemplate.doInsert（MongoTemplate.java:1048）在org.springframework.data.mongodb.core.MongoTemplate.insert（MongoTemplate.java:988）在org.springframework.data.mongodb.repository.support.SimpleMongoRepository.save（SimpleMongoRepository.java:80）在sun.reflect.NativeMethodAccessorImpl.invoke0（本机方法）处在sun.reflect.NativeMethodAccessorImpl.invoke（NativeMethodAccessorImpl.java:62）在sun.reflect.DelegatingMethodAccessorImpl.invoke（DelegatingMethodAccessorImpl.java:43）在java.lang.reflect.Method.invoke（Method.java:498）在org.springframework.data.repository.core.support.RepositoryComposition $ RepositoryFragments.invoke（RepositoryComposition.java:377）在org.springframework.data.repository.core.support.RepositoryComposition.invoke（RepositoryComposition.java:200）在org.springframework.data.repository.core.support.RepositoryFactorySupport $ ImplementationMethodExecutionInterceptor.invoke（RepositoryFactorySupport.java:629）在org.springframework.aop.framework.ReflectiveMethodInvocation.proceed（ReflectiveMethodInvocation.java:185）在org.springframework.data.repository.core.support.RepositoryFactorySupport $ QueryExecutorMethodInterceptor.doInvoke（RepositoryFactorySupport.java:593）在org.springframework.data.repository.core.support.RepositoryFactorySupport $ QueryExecutorMethodInterceptor.invoke（RepositoryFactorySupport.java:578）在org.springframework.aop.framework.ReflectiveMethodInvocation.proceed（ReflectiveMethodInvocation.java:185）在org.springframework.data.projection.DefaultMethodInvokingMethodInterceptor.invoke（DefaultMethodInvokingMethodInterceptor.java:59）在org.springframework.aop.framework.ReflectiveMethodInvocation.proceed（ReflectiveMethodInvocation.java:185）在org.springframework.aop.interceptor.ExposeInvocationInterceptor.invoke（ExposeInvocationInterceptor.java:92）在org.springframework.aop.framework.ReflectiveMethodInvocation.proceed（ReflectiveMethodInvocation.java:185）在org.springframework.data.repository.core.support.SurroundingTransactionDetectorMethodInterceptor.invoke（SurroundingTransactionDetectorMethodInterceptor.java:61）在org.springframework.aop.framework.ReflectiveMethodInvocation.proceed（ReflectiveMethodInvocation.java:185）在org.springframework.aop.framework.JdkDynamicAopProxy.invoke（JdkDynamicAopProxy.java:212）在com.sun.proxy。$ Proxy127.save（未知来源）在com.gt.ffm.restful.Application.run（Application.java:94）在org.springframework.boot.SpringApplication.callRunner（SpringApplication.java:797） ...还有11个

ConverterNotFoundException：在集合中插入GeoJsonPoint时，GeoJsonPoint会键入文档
