Migrating StringEscapeUtils.escapeSql from commons.lang

由 南楼画角 提交于 2019-12-22 04:06:09
问题 I have started to migrate commons.lang 2 to commons.lang3. According to https://commons.apache.org/proper/commons-lang/article3_0.html StringEscapeUtils.escapeSql This was a misleading method, only handling the simplest of possible SQL cases. >As SQL is not Lang's focus, it didn't make sense to maintain this method. Understand it but what is recommended to use instead of it? Clarification Can you recommend a third party that perform simple escapeSql similar to StringEscapeUtils.escapeSql? 回答1

由 徘徊边缘 提交于 2019-12-21 03:13:08
问题 I couldn't find any explanation why StringEscapeUtils was deprecated from Apache Lang3 v3.7. https://commons.apache.org/proper/commons-lang/apidocs/org/apache/commons/lang3/StringEscapeUtils.html What are we supposed to use now for HTML escaping/unescaping 回答1: The class was moved from package org.apache.commons. lang3 to org.apache.commons. text You can replace the deprecated library easily: In your build.gradle: implementation 'org.apache.commons:commons-text:1.8' And in your class using

In what format does ToStringBuilder.reflectionToString(Object) display dates?

由 こ雲淡風輕ζ 提交于 2019-12-11 05:48:31
问题 In what format does ToStringBuilder.reflectionToString(Object) display dates? According to the Apache Commons Lang 2.4 documentation, ToStringBuilder.reflectionToString(Object) delegates to ReflectionToStringBuilder.toString(Object) which "Builds a toString value using the default ToStringStyle through reflection." So, in what format does the default ToStringStyle display dates? 回答1: DefaultToStringStyle is just an immutable subclass of ToStringStyle , so it falls back on that for handling.

Maybe Commons Lang will have AnnotationUtils some day. What are people using to query for Annotations? 回答1: With version 2.5.6 of Spring, it was possible to use spring.jar (2.8 MB) as

Alternative to using StringEscapeUtils.escapeJavaScript() in commons lang3

由 别来无恙 提交于 2019-12-06 17:09:31
问题 I've been tasked with updating our code from using org.apache.commons.lang to org.apache.commons.lang3 and I've found that the newer version of StringEscapeUtils no longer has the method escapeJavaScript() however we were using this in quite a few places throughout our code. I've been reading through the documentation and it seems that the whole of StringEscapeUtils was rewritten for lang3 (see release notes lang 3.3.2) and with this rewrite they removed escapeJavaScript() however they haven

Parsing numbers safely and locale-sensitively

由 一曲冷凌霜 提交于 2019-12-04 01:07:50
问题 Java's NumberFormat is 1) non thread-safe (which can be worked around with a ThreadLocal ); 2) inconvenient to use correctly for the simplest use case when I know whether the string should contain int, long, or double, and want an API like: int parseInt(String str, Locale locale) throws ParseException; int parseInt(String str, int defaultValue, Locale locale); long parseLong(String str, Locale locale) throws ParseException; long parseLong(String str, long defaultValue, Locale locale); double
