我在用mybatis generator生成代码后，执行查询语句时，Oracle里的Date类型字段只精确到年月日，后面时分秒都为零。
后来发现是jdbcType问题，改成 jdbcType="TIMESTAMP" 就可以。（原先默认生成时是jdbcType="DATE"）
ps：实体类里Date是Java.util.Date包里的，不是java.sql.Date，否则也会只精确到年月日
实体类
package com.pcmall.domain.sale.erps;import java.util.Date;public class Synnexlogs {private String sender;private String receiver;private Date calltime;private String inputparam;private String outputparam;private String type;private String remark;public String getSender() {return sender;}public void setSender(String sender) {this.sender = sender == null ? null : sender.trim();}public String getReceiver() {return receiver;}public void setReceiver(String receiver) {this.receiver = receiver == null ? null : receiver.trim();}public Date getCalltime() {return calltime;}public void setCalltime(Date calltime) {this.calltime = calltime;}public String getInputparam() {return inputparam;}public void setInputparam(String inputparam) {this.inputparam = inputparam == null ? null : inputparam.trim();}public String getOutputparam() {return outputparam;}public void setOutputparam(String outputparam) {this.outputparam = outputparam == null ? null : outputparam.trim();}public String getType() {return type;}public void setType(String type) {this.type = type == null ? null : type.trim();}public String getRemark() {return remark;}public void setRemark(String remark) {this.remark = remark == null ? null : remark.trim();}}
