在MyBatis中,可以使用TypeHandler來實(shí)現(xiàn)對日志中數(shù)據(jù)的脫敏處理。TypeHandler是MyBatis中用于處理JDBC類型與Java類型之間轉(zhuǎn)換的接口,通過自定義TypeHandler來實(shí)現(xiàn)對特定數(shù)據(jù)的脫敏處理。
具體步驟如下:
public class SensitiveDataHandler implements TypeHandler<String> {
@Override
public void setParameter(PreparedStatement ps, int i, String parameter, JdbcType jdbcType) throws SQLException {
// 對參數(shù)進(jìn)行脫敏處理
String sensitiveData = desensitize(parameter);
ps.setString(i, sensitiveData);
}
@Override
public String getResult(ResultSet rs, String columnName) throws SQLException {
// 獲取查詢結(jié)果并進(jìn)行脫敏處理
String sensitiveData = desensitize(rs.getString(columnName));
return sensitiveData;
}
@Override
public String getResult(ResultSet rs, int columnIndex) throws SQLException {
// 獲取查詢結(jié)果并進(jìn)行脫敏處理
String sensitiveData = desensitize(rs.getString(columnIndex));
return sensitiveData;
}
@Override
public String getResult(CallableStatement cs, int columnIndex) throws SQLException {
// 獲取查詢結(jié)果并進(jìn)行脫敏處理
String sensitiveData = desensitize(cs.getString(columnIndex));
return sensitiveData;
}
// 自定義脫敏處理方法
private String desensitize(String data) {
// 進(jìn)行具體的脫敏處理,例如將手機(jī)號碼中間四位替換為*
return data.replaceAll("(\\d{3})\\d{4}(\\d{4})", "$1****$2");
}
}
<typeHandlers>
<typeHandler handler="com.example.SensitiveDataHandler"/>
</typeHandlers>
public class User {
@MappedJdbcType(jdbcType = JdbcType.VARCHAR, typeHandler = SensitiveDataHandler.class)
private String phone;
// getter and setter
}
通過以上步驟,就可以實(shí)現(xiàn)對MyBatis日志中指定數(shù)據(jù)的脫敏處理。當(dāng)MyBatis執(zhí)行SQL查詢時(shí),會(huì)自動(dòng)調(diào)用TypeHandler中的方法對數(shù)據(jù)進(jìn)行處理,從而實(shí)現(xiàn)日志中數(shù)據(jù)的脫敏。
