Spring and SPRINGMVC internationalization applications

Objective:

@1 the text displayed in the view layer is internationalized

@2 Show internationalization after data validation

@3 allows customers to automatically select internationalization via hyperlink parameters

1: Configure internationalization classes in Spring.xml to allow container management internationalization

2: Display internationalization on the page: You can use the spring label <st:message code= "UserName" ></st:message>

@2 Data validation

1: Code-level Data validation: Automatic assembly Messagesource source Java code layer gets error messages in different languages based on different regions and adds error messages to the results

2: Attribute class data validation: Use custom data validation annotations, create bean,l in springmvc.xml to set attribute data validation, and reference internationalized Messagesource to make data validation internationalized

@3: Use the Localechangeinterceptor interceptor to intercept the value of the specified parameter, and then use the Sessionlocaleresolver override to store the value of the locale by default in the session

Spring.xml
