在使用Liquibase增加字段并设置默认值时,可以使用`defaultValue`属性来设置默认值。在Liquibase的change set中,可以使用`addColumn`标签来定义要添加的列,并在该标签内使用`defaultValue`属性来设置默认值。例如:
```xml
<changeSet id="1" author="your_name">
<addColumn tableName="your_table_name">
<column name="your_column_name" type="your_column_type" defaultValue="your_default_value"/>
</addColumn>
</changeSet>
在上述代码中,`your_table_name`是要添加列的数据表名称,`your_column_name`是要添加的列名,`your_column_type`是要添加的列的数据类型,`your_default_value`是要设置的默认值。通过在`addColumn`标签的`defaultValue`属性中指定默认值,即可将默认值添加到新添加的列中。
请注意,以上仅为示例代码,实际使用时请将`your_table_name`、`your_column_name`、`your_column_type`和`your_default_value`替换为实际的表名、列名、列类型和默认值。<span class="em">1</span><span class="em">2</span><sp
