public final class ConfigurationClient
This class provides a client that contains all the operations for ConfigurationSetting, FeatureFlagConfigurationSetting or SecretReferenceConfigurationSetting in Azure App Configuration Store. Operations allowed by the client are adding, retrieving, deleting, set read-only status ConfigurationSettings, and listing settings or revision of a setting based on a SettingSelector.
Additionally, this class allows to add an external synchronization token to ensure service requests receive up-to-date values. Use the updateSyncToken(String token) method.
Getting Started
In order to interact with the App Configuration service you'll need to create an instance of the ConfigurationClient class. To make this possible you'll need the connection string of the configuration store. Alternatively, you can use AAD authentication via Azure Identity to connect to the service.
- Connection string, see connectionString(String connectionString).
- Azure Active Directory, see credential(TokenCredential tokenCredential).
Instantiating a synchronous Configuration Client
ConfigurationClient configurationClient = new ConfigurationClientBuilder()
.connectionString(connectionString)
.buildClient();
View ConfigurationClientBuilder for additional ways to construct the client.
App Configuration support multiple operations, such as create, update, retrieve, and delete a configuration setting. See methods in client level class below to explore all capabilities that library provides.
For more configuration setting types, see FeatureFlagConfigurationSetting and SecretReferenceConfigurationSetting.
Add Configuration Setting
The addConfigurationSetting(ConfigurationSetting setting) method can be used to add a configuration setting in the Azure App Configuration.
The sample below shows how to add a setting with the key "prodDBConnection", label "westUS" and value "db_connection" using ConfigurationClient.
ConfigurationSetting setting = configurationClient.addConfigurationSetting(new ConfigurationSetting()
.setKey("prodDBConnection")
.setLabel("westUS")
.setValue("db_connection"));
System.out.printf("Key: %s, Label: %s, Value: %s", setting.getKey(), setting.getLabel(), setting.getValue());
Note: For asynchronous sample, refer to ConfigurationAsyncClient.
Update Configuration Setting
The setConfigurationSetting(ConfigurationSetting setting) method can be used to update a configuration setting in the Azure App Configuration.
The sample below shows how to update setting's value "db_connection" to "updated_db_connection"
ConfigurationSetting setting = configurationClient.setConfigurationSetting(new ConfigurationSetting()
.setKey("prodDBConnection")
.setLabel("westUS")
.setValue("db_connection"));
System.out.printf("Key: %s, Label: %s, Value: %s", setting.getKey(), setting.getLabel(), setting.getValue());
// Update the value of the setting to "updated_db_connection".
setting = configurationClient.setConfigurationSetting(new ConfigurationSetting()
.setKey("prodDBConnection")
.setLabel("westUS")
.setValue("updated_db_connection"));
System.out.printf("Key: %s, Label: %s, Value: %s", setting.getKey(), setting.getLabel(), setting.getValue());
Note: For asynchronous sample, refer to ConfigurationAsyncClient.
Get Configuration Setting
The getConfigurationSetting(ConfigurationSetting setting) method can be used to get a configuration setting in the Azure App Configuration.
The sample below shows how to retrieve the setting with the key "prodDBConnection".
ConfigurationSetting setting = configurationClient.getConfigurationSetting(new ConfigurationSetting()
.setKey("prodDBConnection")
.setLabel("westUS"));
System.out.printf("Key: %s, Value: %s", setting.getKey(), setting.getValue());
Note: For asynchronous sample, refer to ConfigurationAsyncClient.
Delete Configuration Setting
The deleteConfigurationSetting(ConfigurationSetting setting) method can be used to delete a configuration setting in the Azure App Configuration.
The sample below shows how to delete the setting with the key "prodDBConnection".
ConfigurationSetting setting = configurationClient.deleteConfigurationSetting(new ConfigurationSetting()
.setKey("prodDBConnection")
.setLabel("westUS"));
System.out.printf("Key: %s, Value: %s", setting.getKey(), setting.getValue());
Note: For asynchronous sample, refer to ConfigurationAsyncClient.
Set the Configuration Setting to read-only
The setReadOnly(ConfigurationSetting setting, boolean isReadOnly) method can be used to conditionally set a configuration setting to read-only in the Azure App Configuration.
The sample below shows how to conditionally set the setting to read-only with the key "prodDBConnection".
ConfigurationSetting setting = configurationClient.setReadOnly(new ConfigurationSetting()
.setKey("prodDBConnection")
.setLabel("westUS"),
true);
System.out.printf("Key: %s, Value: %s", setting.getKey(), setting.getValue());
Note: For asynchronous sample, refer to ConfigurationAsyncClient.
Clear read-only of the Configuration Setting
The setReadOnly(ConfigurationSetting setting, boolean isReadOnly) method can be used to conditionally clear read-only of the setting in the Azure App Configuration.
The sample below shows how to conditionally clear read-only of the setting with the key "prodDBConnection".
ConfigurationSetting setting = configurationClient.setReadOnly(new ConfigurationSetting()
.setKey("prodDBConnection")
.setLabel("westUS"),
false);
System.out.printf("Key: %s, Value: %s", setting.getKey(), setting.getValue());
Note: For asynchronous sample, refer to ConfigurationAsyncClient.
List Configuration Settings
The listConfigurationSettings(SettingSelector selector) method can be used to list configuration settings in the Azure App Configuration.
The sample below shows how to list all settings that use the key "prodDBConnection".
SettingSelector settingSelector = new SettingSelector().setKeyFilter("prodDBConnection");
configurationClient.listConfigurationSettings(settingSelector).forEach(setting -> {
System.out.printf("Key: %s, Value: %s", setting.getKey(), setting.getValue());
});
Note: For asynchronous sample, refer to ConfigurationAsyncClient.
List revisions of a Configuration Setting
The listRevisions(SettingSelector selector) method can be used to list all revisions of a configuration setting in the Azure App Configuration.
The sample below shows how to list all revision of a setting that use the key "prodDBConnection".
SettingSelector settingSelector = new SettingSelector().setKeyFilter("prodDBConnection");
configurationClient.listRevisions(settingSelector).streamByPage().forEach(resp -> {
System.out.printf("Response headers are %s. Url %s and status code %d %n", resp.getHeaders(),
resp.getRequest().getUrl(), resp.getStatusCode());
resp.getItems().forEach(value -> {
System.out.printf("Response value is %d %n", value);
});
});
Note: For asynchronous sample, refer to ConfigurationAsyncClient.
