JSR 303 is the standard framework that Java provides for the validation of the bean data, which is already included in EE 6. 0. JSR303Specify a validation rule by annotating annotations on bean properties that are similar to @notnull, @Max, and so on, and validate the bean with a standard authentication interface:---------------------------------------------------------------------------Annotation Description-------------------------------------------

In the project, most of the front-end checks are used, such as the JS check in the page and the form form using the bootstrap checksum. However, for higher security requirements, it is recommended to verify on the service side.Service-side check: Control Layer Controller: Verifies the legality of the parameters requested by the page. In the server-side control layer controller checksum, the client type is not distinguished. Business Layer Service (use more): Mainly check the key bus

Id = 303 Hibernate validator is a reference implementation of bean validation. hibernate validator provides all built-in constraint implementations in the JSR 303 specification, in addition to some additional constraint.

JSR 207 Java Process Definition for Java aims to explore and standardize the relationships between Process Languages (such as BPEL), Java languages, and J2EE platforms. Java Process Definition (JSR 207) defines a more advanced programming model that allows developers to write business processes. Its Standardization is very encouraging, it can improve the abstract level of enterprise-level application develo

Js Content Repository API (JSR-170) posts Final Draft The JSR-170 Expert Group submitted the final draft of the JSR specification for Java Content Repository (JCR), which JCR the specification of "content services", such as based on the author's version, Full-text search, excellent authorization access control, content classification, and content event monitori

In a Web application, it is necessary for the user to submit form data in order to ensure the validity of the data, and the validation of the foreground client, such as JavaScript, is not always secure and reliable, so we need a robust background validation framework to handle this problem. Fortunately, Java has released the JSR-303 interface standard, and there are many vendors that implement this standard, and the Hibernate Validator Verification fr

　About Bean Validation　　The JSR 303-bean Validation is a sub-specification in Jree6, and theJSR 303-bean Validation focuses on the following practical issues:　　At any time, when you are dealing with the business logic of an application, data validation is something you have to consider and face. The application must have some means to ensure that the input data is semantically correct. In the usual case, the application is layered and different layers

Today, Red Hat submitted the final draft of JSR-299To JCP.
