The micro-mvc framework enables all controller, servicebean, dao and sql scripts to support dynamic hot deployment and debugging with the help of the nhmicro framework and groovy technology.

Controller layer

Use annotated MicroUrlMapping to set url address in Controller layer groovy

Comments on the class must have and act as the root path

Set subpaths in each method

For example, the test method in the following groovy can call url to / testController/test

The method parameters are fixed as HttpServletRequest request and HttpServletResponse response.

@ MicroUrlMapping (name= "/ testController") class TestController extends MicroControllerTemplate {public String tableName= "micro_test3"; public String getTableName (HttpServletRequest httpRequest) {return tableName;} @ MicroUrlMapping (name= "/ test") public void test (HttpServletRequest request, HttpServletResponse response) {

You can inherit MicroControllerTemplate to obtain the default add, delete, modify and query function http API. But you need to write the calling procedure of super and set url in controller.

@ MicroUrlMapping (name= "/ delInfo") public void delInfo (HttpServletRequest httpRequest, HttpServletResponse httpResponse) {super.delInfo (httpRequest, httpResponse);}

Service layer

It is recommended that the service function and the controller layer function be implemented in the same groovy. If you have to separate the service layer groovy

Do not want to use GroovyExecUtil to display the call. The proxy interface object of the service layer groovy can be injected by annotating InjectGroovy.

When a member variable of an InjectGroovy annotation is encountered when loading groovy, a proxy object for the member interface is automatically generated and injected.

The function of the proxy object is to call a method with the same name as the interface in the groovy specified by name.

@ InjectGroovy (name= "testGroovy") public ITest test

If the service layer object is written by traditional java, or microdao's mapper object, you can use Resource to inject annotations from spring.

@ Resource public TestRep testRep

Aop mechanism

Aop proxy mechanism is provided when loading groovy. Transaction aop and data source switching aop are provided by default.

Transaction aop, which can recognize Transactional annotations when loading, and realize transaction control.

Do not write specific functional agents on your own.

To enable the proxy, you need to set the @ MicroAop annotation in the class of groovy to specify the proxy class.

@ MicroAop (name= [MicroDefaultLogProxy.class,MicroTMProxy.class,MicroDbProxy.class], property= [",", "]) @ MicroUrlMapping (name=" / testController ") class TestController extends MicroControllerTemplate {

Dao layer

MicroDao supports both mysql and oracle

Advantages of MicroDao over mybatis:

1the SQL script supports hot deployment to take effect in real time after modification.

2the mapping relationship between the bean and the database field is set to bean through annotations, but does not have to be reflected in the sql script.

3The jsp script supports writing similar to jsp, and there is no need to distinguish between select and update using different tags, so it is more flexible.

4, no need to use plug-ins, built-in support for physical paging.

5. No plug-ins are required, and the standard addition, deletion, modification and query function for bean is supported in the built-in.

6, do not need to use plug-ins, built-in support for read-write separation, sub-library sub-table.

7. Dynamic fields are supported for mysql5.7.

Support mapper, template and non-orm modes to support business systems

1Powermapper means that dao instances are automatically generated at runtime through scanning interfaces.

2. Dao template refers to the generation of a template subclass by inheriting the dao standard parent class

3. Non-orm means that you can perform more flexible database operations on non-orm by using microDao instances directly.
