Is it throwing an exception directly? Is it to keep the former and ignore the latter? Is it to ignore the former and keep the latter? Or does it allow a certain form of coexistence (such as the attributes of the latter overriding the former)?</p><p>Currently, the only configuration class type in dubbo and the configuration modes/strategies allowed by finding multiple instances of a unique configuration type are as follows.</p><p><strong>Unique configuration class type</strong></p><p><code>ApplicationConfig</code>, <code>MonitorConfig</code>, <code>MetricsConfig</code>, <code>SslConfig</code>, <code>ModuleConfig</code>.</p><p>The first four belong to the application level, and the last one belongs to the module level.</p><p><strong>configuration mode</strong></p><ul><li><code>strict</code>: Strict mode. Throw an exception directly.</li><li><code>override</code>: override mode. Ignore the former and keep the latter.</li><li><code>ignore</code>: ignore pattern. Ignore the latter and keep the former.</li><li><code>override_all</code>: attribute override mode. No matter whether the attribute value of the former is empty or not, the attribute of the latter is overwritten/set on the former.</li><li><code>override_if_absent</code>: attribute override mode if absent. Only when the corresponding attribute value of the former is empty, can the attribute of the latter be overwritten/set on the former.</li></ul><p>Note: The latter two also affect property overrides for configuration instances. Because dubbo has multiple configuration methods, that is, there are multiple configuration sources, and the configuration sources also have priorities. For example, a <code>ServiceConfig</code> is configured through xml and the attribute <code>version=1.0.0</code> is specified. At the same time, we configure <code>dubbo.service.{interface}.version=2.0.0</code> in the external configuration (configuration center), Before the <code>config-mode</code> configuration item is introduced, according to the original configuration source priority, <code>version=2.0.0</code> of the final instance. However, after the <code>config-mode</code> configuration item is introduced, the configuration priority rules are no longer so strict, that is, if <code>config-mode is override_all</code> is specified, it is <code>version=2.0.0</code>, if <code>config-mode is override_if_absent</code> If it is <code>version=1.0.0</code>, if <code>config-mode</code> is other values, the property setting/overwriting will follow the original configuration priority.</p><p><strong>Configuration method</strong></p><p>The configured key is <code>dubbo.config.mode</code>, the configured values are as described above, and the default policy value is <code>strict</code>. A sample configuration is shown below</p><div class=highlight><pre tabindex=0 style=color:#93a1a1;background-color:#002b36;-moz-tab-size:4;-o-tab-size:4;tab-size:4><code class=language-properties data-lang=properties><span style=display:flex><span><span style=color:#586e75># JVM -D</span> |
