Question

我刚开始照顾其他人开发的代码。它是基于使用Spring Data和Hibernate的规范模式设计的。

简而言之，如果我尝试使用字符串，布尔或整数字段进行搜索，它可以正常工作。例如，当我使用state == SP搜索/过滤时，我得到了结果，我可以看到硅藻土字段已正确填写。此外，我看到hibernate在这种情况下没有抱怨无效数据：

当我使用“state == SP”成功搜索时，从我的控制台复制 ... TRACE 2450 --- [nio-9000-exec-2] o.h.type.descriptor.sql.BasicExtractor：提取值（[created17_12_]：[TIMESTAMP]） - [2013-07-12T06：53：47] ......

然而，当我使用datetime搜索/过滤时，我得到了这个问题中总结的错误。例如：我搜索“createdDate == 2014-06-03T18：48：33”，我得到：

2018-03-23 17:38:17.547 ERROR 2450 --- [nio-9000-exec-5] o.a.c.c.C.[.[.[/].[dispatcherServlet]    : Servlet.service() for servlet [dispatcherServlet] in context with path [] threw exception [Request processing failed; nested exception is org.springframework.dao.InvalidDataAccessApiUsageException: Parameter value [2014-06-03T18:48:33] did not match expected type [java.time.LocalDateTime (n/a)]; nested exception is java.lang.IllegalArgumentException: Parameter value [2014-06-03T18:48:33] did not match expected type [java.time.LocalDateTime (n/a)]] with root cause

调用findAll时存储库引发错误：

@Repository
@Transactional
public class ApiServiceImpl implements ApiService {

    @PersistenceContext
    private EntityManager em;

    @Override
    public <T> Page<T> list(Class<T> clazz, Class<? extends JpaSpecificationExecutor<T>> clazz2, String search,
            Pageable pageable, Class<? extends Specification<T>> specClazz) {
        JpaSpecificationExecutor<T> repository = new JpaRepositoryFactory(em).getRepository(clazz2);

        SpecificationBuilder<T> builder = new SpecificationBuilder<>(specClazz);
        Pattern pattern = Pattern.compile("(\\w+.*?)(==|!=|<|<=|>|>=|=|===)((\\*|\\w+).*?);");
        Matcher matcher = pattern.matcher(search + ";");
        while (matcher.find()) {
            builder.with(matcher.group(1), matcher.group(2), matcher.group(3));
        }

        org.springframework.data.jpa.domain.Specification<T> spec = builder.build();
        Page<T> page = repository.findAll(spec, pageable);

        return page;
    }
...

ApiService接口

import org.springframework.data.domain.Page;
import org.springframework.data.domain.Pageable;
import org.springframework.data.jpa.repository.JpaSpecificationExecutor;

import br.com.mycompany.specification.Specification;

public interface ApiService {

    <T> Page<T> list(Class<T> clazz, Class<? extends JpaSpecificationExecutor<T>> clazz2, String search, Pageable pageable, Class<? extends Specification<T>> customSpec);

    <T> T get(Class<T> clazz, Class<? extends JpaSpecificationExecutor<T>> clazz2, String search, Class<? extends Specification<T>> customSpec);
}

LocalDateTimeSerializer：

    import java.io.IOException;
    import java.time.LocalDateTime;
    import java.time.format.DateTimeFormatter;

    import com.fasterxml.jackson.core.JsonGenerator;
    import com.fasterxml.jackson.databind.JsonSerializer;

    public class LocalDateTimeSerializer extends JsonSerializer<LocalDateTime> {

        @Override
        public void serialize(LocalDateTime dateTime, JsonGenerator generator,
                com.fasterxml.jackson.databind.SerializerProvider provider)
                throws IOException, com.fasterxml.jackson.core.JsonProcessingException {
            if (dateTime == null) {
                generator.writeNull();
            } else {
                generator.writeString(dateTime.format(DateTimeFormatter.ofPattern("yyyy-MM-dd'T'HH:mm:ss")));
            }
        }

}

型号：

import java.io.Serializable;
import java.time.LocalDateTime;
import java.util.HashMap;
import java.util.Map;
import javax.persistence.Column;
import javax.persistence.Convert;
import javax.persistence.Entity;
import javax.persistence.FetchType;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;
import javax.persistence.JoinColumn;
import javax.persistence.ManyToOne;
import javax.persistence.Table;
import javax.persistence.Transient;

import br.com.mycompany.converter.BooleanNumberConverter;
import br.com.mycompany.converter.ReleaseCategoryTypeConverter;
import br.com.mycompany.converter.ReleaseStatusTypeConverter;
import br.com.mycompany.serializer.LocalDateTimeSerializer;


@Entity
@Table(name = "releases")
@JsonInclude(Include.NON_NULL)
public class Release implements Serializable {

    private static final long serialVersionUID = 1L;

    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    @Column(name = "id", nullable = false)
    private Long id;

    @Column(name = "state", length = 2)
    private String state;

    @JsonSerialize(using = LocalDateTimeSerializer.class)
    @Column(name = "created_date", nullable = false, insertable = true, updatable = false)
    private LocalDateTime createdDate = LocalDateTime.now();

//other fields, constructors, gets/sets not relevant

数据库是Mysql。如果我通过Workbench在MySql中搜索straigh，我可以看到这个样本：

select created_date from releases

'0000-00-00 00:00:00'
'0000-00-00 00:00:00'
...
'2013-09-28 09:19:23'
'2013-09-28 09:19:59'

通过锁定关闭格式，我觉得LocalDateTimeSerializer.serialize是正确的。

任何线索都将受到高度赞赏。

****编辑

仔细阅读后Hibernate 4 with java.time.LocalDate and DATE() construct，我查看了哪些罐子版本，据我所知，如果我的罐子有问题，我没有找到任何提示。我在下面添加了两个打印屏幕，显示我正在使用哪个jar版本。另外，我正在粘贴使用的三种方法。所有这三个导致上述相同的错误。

库：

和

使用的方法完全没有区别：

1 - 从列中删除了@JsonSerialize和@Converter。我的意思是：

//@JsonSerialize(using = LocalDateTimeSerializer.class)
//@Convert(converter = MovingLocalDateTimeConverter.class)
@Column(name = "created_date", nullable = false, insertable = true, updatable = false)
private LocalDateTime createdDate;

2 - 添加了JsonSerialize。我的意思是：

import java.io.IOException;
import java.time.LocalDateTime;
import java.time.format.DateTimeFormatter;

import com.fasterxml.jackson.core.JsonGenerator;
import com.fasterxml.jackson.databind.JsonSerializer;

public class LocalDateTimeSerializer extends JsonSerializer<LocalDateTime> {

    @Override
    public void serialize(LocalDateTime dateTime, JsonGenerator generator,
            com.fasterxml.jackson.databind.SerializerProvider provider)
            throws IOException, com.fasterxml.jackson.core.JsonProcessingException {
        if (dateTime == null) {
            generator.writeNull();
        } else {
            generator.writeString(dateTime.format(DateTimeFormatter.ofPattern("yyyy-MM-dd'T'HH:mm:ss")));
        }
    }

}

和

@JsonSerialize(using = LocalDateTimeSerializer.class)
@Column(name = "created_date", nullable = false, insertable = true, updatable = false)
private LocalDateTime createdDate;

3 - 添加了转换器。我的意思是，

import java.time.DateTimeException;
import java.time.LocalDateTime;
import java.time.format.DateTimeFormatter;
import javax.persistence.AttributeConverter;
import javax.persistence.Converter;

@Converter
public class MovingLocalDateTimeConverter implements AttributeConverter<LocalDateTime, String> {

    //private DateTimeFormatter fmt = DateTimeFormatter.ofPattern("yyyy-MM-dd HH:mm:ss");
    private DateTimeFormatter fmt = DateTimeFormatter.ofPattern("yyyy-MM-dd'T'HH:mm:ss");

    @Override
    public String convertToDatabaseColumn(LocalDateTime value) {
        return (value != null) ? value.format(fmt) : null;
    }

    @Override
    public LocalDateTime convertToEntityAttribute(String value) {
        return convertLocalDateTime(value);
    }

    private LocalDateTime convertLocalDateTime(String value) {
        try {
            return (value != null) ? LocalDateTime.parse(value.substring(0, 19), fmt) : null;
        } catch (DateTimeException e) {
            return null;
        }
    }

}

和

@Convert(converter = MovingLocalDateTimeConverter.class)
@Column(name = "created_date", nullable = false, insertable = true, updatable = false)
private LocalDateTime createdDate;

所有当前错误都没有改变。
