code obfuscation techniques

GreenDao custom type converter and code obfuscation configuration in the Android ORM series, ormgreendao Sometimes, our entity classes have some attributes, but there is no corresponding type in the database. In this case, we need to customize the converter for type conversion. The most common processing is the Date type.

generatedtype = schema.addEntity("Demo");type.addStringProperty("test").customType("java.util.Date","cn.edu.zafu.greendao.db.converter.DateStringConverter");AddProperty is the corresponding type in the database, where we store it as a string, so it is addstringproperty, and then through the customtype function to specify the type of the entity class, here is Java.util.Date, followed by the full class name of our type converter. Then try inserting a piece of data into the database, and we'll fi
