java - Springs CustomDateEditor luring to make mistakes? -


let me start couple of facts:

simpledateformat not thread safe proven here: andy grove's blog: simpledateformat , thread safety

when want convert strings parameters of request other objects (like java.util.date) can use java beans' property editor support.

for java.util.date spring offers class conversion you: customdateeditor.

the constructor of class required dateformat first argument. if registration of custom property editors happens each request: injecting simpledateformat (the standard implementation of dateformat) suggested here (please scroll down or use browser's search simpled...), run trap.

what thread safe solution?

configure simpleformatdate scope="request", new instance of simpledateformat instantiated each request.

<bean id="simpledateformat" class="java.text.simpledateformat" scope="request">   <constructor-arg value="dd-mm-yyyy"/> </bean>

note: may need configure proxy

<beans   xmlns:aop="http://www.springframework.org/schema/aop"   ...   xsi:schemalocation="...     http://www.springframework.org/schema/aop      http://www.springframework.org/schema/aop/spring-aop-3.0.xsd">    <bean id="simpledateformat" class="java.text.simpledateformat" scope="request">     <constructor-arg value="dd-mm-yyyy"/>     <aop:scoped-proxy />   </bean>   ...
