Learn extjs5 with me (29 -- add module and menu Definition [2 create java bean])

Create bean files in java for the four modules added in the previous section. After the preceding table is created, you need to create a java bean file. You need to add several support classes before creating them. Create the annotation package in com. jfok. server. common, and then add two class libraries below. These two are custom annotation classes. It is used to annotate the information of each module and the information of each field in the module.

Package com. jfok. server. common. annotation; import java. lang. annotation. retention; import java. lang. annotation. retentionPolicy;/*** used to comment out the module ** @ author jiangfeng */@ Retention (RetentionPolicy. RUNTIME) public @ interface TableDefine {// id of this table, which is a four-digit int id (); // Module name String title (); // module abbreviation String shortname () default ""; // module group name String group (); // whether the primary key of the module can be classified. If yes, it can be defined as "2, 2", indicating that there are three levels, each level of code is 2 bits, // For example, the accounting subject can be defined as // 10 // 1001 // 100101 // 100102 // 100102 // 1002 //...... string codeLevel () default ""; // whether the module has an attachment boolean attachment () default false ;}

Package com. jfok. server. common. annotation; import java. lang. annotation. retention; import java. lang. annotation. retentionPolicy;/*** used to comment out each field in the module ** @ author jiangfeng **/@ Retention (RetentionPolicy. RUNTIME) public @ interface FieldDefine {String title (); int number () default 0; String remark () default ""; boolean nameField () default false; boolean hidden () default false; String fieldGroup () default "default group ";}

Create the package system in com. jfok. server. hibernate and put all the bean files used by the system in this directory. Create an interface file first:

Package com. jfok. server. hibernate. system;/*** classes with this interface are all control classes of the system module ** @ author jfok **/public interface _ IModuleControlInterface {}

Create _ ModuleGroup. java

Package com. jfok. server. hibernate. system; import java. io. serializable; import javax. persistence. column; import javax. persistence. entity; import javax. persistence. id; import com. jfok. server. common. annotation. fieldDefine; import com. jfok. server. common. annotation. tableDefine;/*** module grouping class, each module has a major grouping ** @ author jfok 2012.11.7 */@ SuppressWarnings ("serial") @ Entity@org.hibernate.annotations.Entity (dynamicUpdate = true) @ TableDefine (group = "system module", id = 9901, title = "module group") public class _ ModuleGroup implements _ IModuleControlInterface, serializable {public static final String TITLE = "tf_title"; @ Id @ FieldDefine (title = "module Group No.", number = 10) @ Column (nullable = false, length = 10) private String tf_moduleGroupId; @ FieldDefine (title = "module group name", nameField = true, number = 20) @ Column (nullable = false, length = 50) private String tf_title; @ FieldDefine (title = "Description", number = 30) private String tf_description; @ FieldDefine (title = "icon address", number = 40) private String tf_iconURL; @ FieldDefine (title = "Remarks", number = 50) private String tf_remark; public _ ModuleGroup () {}// setter and getter}

In the above class, the User-Defined annotation class is used for annotation. One is the Annotation on the class name, and the other is the Annotation on each field. The function of these two types of annotations is that when a module is added in the future, the information of these annotations will be automatically added to the table of the saved module and module fields.

So far, we have created a data table and a java bean file. Now we can develop the content for collaboration in the front and back ends. Directory structure of each file:
