Magento2开发教程-XML配置说明

di.xml 指定或重写Proxy

config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:ObjectManager/etc/config.xsd">
    
    
   preference for="MagentoContactControllerIndexPost" type="InfinityContactControllerIndexPost" />
config>

ps: 重写 block 时如涉及读取组件模板，可能也需要把 phtml 复制到当前 module 中

di.xml 指定或重写某个类中构造函数入参所依赖Proxy

xml version="1.0"?>
config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:ObjectManager/etc/config.xsd">
    
    type name="[Vendor][Module]Xxx">
        arguments>
            
            
            argument name="arg1" xsi:type="object">[Vendor][Module]XxxxxProxyargument>
        arguments>
    type>
config>

di.xml 声明plugin，用于修改目标类若干个method的入参或者返回结果

xml version="1.0"?>
config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:ObjectManager/etc/config.xsd">
    
    type name="MagentoCustomerModelResourceVisitor">
        
        
        
        plugin name="catalogLog"
            type="MagentoCatalogModelPluginLog"
            sortOrder="1"
            disabled="true" />
    type>
config>
