mybatis LocalDateTime轉換

mybatis 3.45版本不做任何處理就可以支持，以上版本可能不能支持。

package com.pasc.medical.esb.pmp.db.handle;

import org.apache.ibatis.type.LocalDateTimeTypeHandler;

import java.sql.ResultSet;
import java.sql.SQLException;
import java.sql.Timestamp;
import java.time.LocalDateTime;
import java.time.ZoneOffset;


public class MLocalDateTimeTypeHandler extends LocalDateTimeTypeHandler{

    @Override
    public LocalDateTime getNullableResult(ResultSet rs, String columnName) throws SQLException {
        Timestamp timestamp = rs.getTimestamp(columnName);
        Long remindTime = timestamp.getTime();
       return LocalDateTime.ofEpochSecond(remindTime,0, ZoneOffset.ofHours(8));
    }
}

package com.pasc.medical.esb.pmp.config;

import com.pamc.mute.idworker.mybatis.GeneratorIdInterceptor;
import com.pasc.medical.esb.pmp.db.handle.MLocalDateTimeTypeHandler;
import org.apache.ibatis.session.Configuration;
import org.apache.ibatis.session.SqlSessionFactory;
import org.apache.ibatis.type.JdbcType;
import org.apache.ibatis.type.TypeHandlerRegistry;
import org.mybatis.spring.boot.autoconfigure.ConfigurationCustomizer;
import org.springframework.beans.BeansException;
import org.springframework.context.ApplicationContext;
import org.springframework.context.ApplicationContextAware;
import org.springframework.context.annotation.Bean;

/**
 * mybatis的自定義配置，添加id-worker自動注入
 *
 */
@org.springframework.context.annotation.Configuration
public class MybatisConfig implements ConfigurationCustomizer {


    @Override
    public void customize(Configuration configuration) {
        // 設置null也返回
        configuration.setCallSettersOnNulls(true);
        // 設置一行都爲null也返回
        configuration.setReturnInstanceForEmptyRow(true);
        configuration.setJdbcTypeForNull(JdbcType.NULL);
        //id自動注入攔截器
        configuration.addInterceptor(new GeneratorIdInterceptor());
        TypeHandlerRegistry typeHandlerRegistry = configuration.getTypeHandlerRegistry();
        typeHandlerRegistry.register(MLocalDateTimeTypeHandler.class);
    }

}

LocalDateTimeTypeHandler 內置的LocalDateTime類型處理。3.45和其它版本不一致
