用法介绍

使用mybatis plugin,配置如下：


<plugin>
    <groupId>org.mybatis.generator</groupId>
    <artifactId>mybatis-generator-maven-plugin</artifactId>
    <version>1.3.2</version>
    <executions>
        <execution>
            <phase>install</phase>
            <id>Generate MyBatis Artifacts</id>
            <goals>
                <goal>generate</goal>
            </goals>
        </execution>
    </executions>
    <configuration>
        <configurationFile>src/main/resources/generatorConfig.xml</configurationFile>
        <overwrite>true</overwrite>
    </configuration>
</plugin>

查看官方对于生成主键的配置的解释

http://www.mybatis.org/generator/configreference/generatedKey.html

generatorConfig.xml 配置


<table schema="hotel_pda" tableName="vg_upload_file">
    <property name="useActualColumnNames" value="false"/>
    <generatedKey column="id" sqlStatement="MySql" identity="true" />
</table>

public int insert(Domain domain) {
	//插入完成后 domain的主键id字段会被赋值，直接返回即可
	domainMapper.insertSelective(domain);
	return domain.getId();
