环境：eclipse+maven
1.首先新建一个maven项目
2.然后把我下面的代码贴到pom.xml里面，数据库用户名密码改成自己的

3.右击项目-run as -maven generate-sources
4.完成了。
备注：有两个类你们可能用得上
Byte2IntegerConverter.java
package com.util;

import java.util.Objects;
public class Byte2IntegerConverter implements Converter<Byte, Integer> {
private static final long serialVersionUID = 1L;

return Objects.isNull(databaseObject) ? null : databaseObject.intValue();
}
@Override
public Byte to(Integer userObject) {
return Objects.isNull(userObject) ? null : userObject.byteValue();
}
@Override
public Class<Byte> fromType() {
return Byte.class;
}
@Override
public Class<Integer> toType() {
return Integer.class;
}
}
Timestamp2DateConverter.java
package com.util;
