When integrating the three SSH frameworks, Hibernate can control the relationship between tables. However, the configuration is slightly neglected and prone to errors. The following code is used. I didn't set the foreign key relationship in the database, but wanted to control it through hibernate. There were two tables, column table (LM) and Course table (KC). They were multi-to-one. Therefore, in the LM pojo class, set public class lm implements java. Io. serializable {// column ID private int

This question is explained in the book by the author:
Tell the compiler that in the future our program will be loaded into the 07c00 for execution.
To tell the truth, "write your own operating system" this book is really good, I do not admire the author's level, but the author's perseverance, can p

Rt.jar is the Java base Class library (a very important package in the Java Core framework),Most of the features include Lang, and Rt.jar default is in the root ClassLoader loading path,So it is superfluous to put it in classpath. The difference between them is as follows: 1. java.*

This class is a tool for loading hibernate resources. Three types of loading classes of JDK are used during resource loading.
1. Current Thread class loader

2. Current Class Loader

3. System Class Loader

The best way to correlate cross-information is to label it. The org mode of Emacs is very powerful in supporting tags.Each title can contain a list of tags at the end. Labels consist of letters, numbers, ' _ ' and ' @ '. There must be a colon before and after the label, such as ': work: ' . You can also declare multiple tags like ': work:urgent: ' . The label is bold by default and has the same color as the title. You can specify a different style for
