XML Schema-based filter configuration

If you have huge count of field or strategy filters configurations you can configure them in XML file XML configuration uses next DTD structure file.

• Example of XML configuration file (filter_configuration.xml)

<?xml version='1.0' encoding='utf-8'?>
<!DOCTYPE config PUBLIC
        "-//json/json-ignore mapping DTD 1.0//EN"
        "https://rkonovalov.github.io/json-ignore-schema-1.0.dtd">
<config>
    <controller class-name="com.example.SessionService">
        <strategy attribute-name="ROLE" attribute-value="USER">

            <filter class="com.example.User">
                <field name="password"/>
            </filter>
        </strategy>
       
    </controller>
</config>

Description of XML tags

• config - main tag
• controller - in this TAG you may set class-name property. Set Service class name where used this configuration
• strategy - this TAG similar SessionStrategy annotation
• filter - this TAG similar FieldFilterSetting annotation

Example of using

@FileFilterSetting(fileName = "filter_configuration.xml")

@RequestMapping(value = "/users/signIn",
             params = {"email", "password"}, method = RequestMethod.POST,
             consumes = {MediaType.APPLICATION_FORM_URLENCODED_VALUE},
             produces = {MediaType.APPLICATION_JSON_VALUE})            
     public User signIn(@RequestParam("email") String email, @RequestParam("password") String password) {
         return userController.signInUser(email, password);
     }

Where

• fileName - is xml configuration file name. XML file should be in /resources/ or sub folders

Auto reloading changed XML files

Also has been added FileWatcher controller which auto reloads changed xml files. Therefore xml configuration files could be change after application starts and controller will correctly reloads all changed files.
