At first glance, it was a bit of a react, but it was very smooth (so forget the details) when you used NG and when you wrote a similar function. Why can't jquery do that? Looked at the specific scene, found that the original JQ Ajax callback has put the response data fool-type in the form of a string parsing. Check GG, found that the domestic solution is not practical JQ in this scenario, but manually create XMLHttpRequest. Although this method is reliable, the previously encapsulated JQ Ajax c

Hibernate operates Blob data and hibernateblob data First, let's look at the database. Create a New BlobTable table in the database. The table has two fields, one id (primary key) and one picture field, which is a Blob field. Then, use Hibernate to write and read data to the database. In the POJO class, the picture attribute uses Blob data. See the operation sou

Given that JPA has been used to achieve object persistence, the leader has always thought that the migration task is easy, but there are still a lot of problems in the actual process. Some of these problems are caused by nonstandard definitions of EJBS, such as mapping number (1) to Boolean, number (n) to string, date mappin
