mybatis 自动映射相关研究碎片

configuration.getTypeAliasRegistry().registerAlias(SysUserRole.class);
configuration.addMapper(SysUserRoleMapper.class);

mapper  resouces  通过 下面进行了处理   .xml  需要跟类全限定名称一致

public MapperAnnotationBuilder(Configuration configuration, Class<?> type) {
  String resource = type.getName().replace('.', '/') + ".java (best guess)";
  this.assistant = new MapperBuilderAssistant(configuration, resource);
  this.configuration = configuration;
  this.type = type;

  sqlAnnotationTypes.add(Select.class);
  sqlAnnotationTypes.add(Insert.class);
  sqlAnnotationTypes.add(Update.class);
  sqlAnnotationTypes.add(Delete.class);

  sqlProviderAnnotationTypes.add(SelectProvider.class);
  sqlProviderAnnotationTypes.add(InsertProvider.class);
  sqlProviderAnnotationTypes.add(UpdateProvider.class);
  sqlProviderAnnotationTypes.add(DeleteProvider.class);
}

默认 maven 打包是不包含java包下的 xml 文件   需要通过pom 进行下列或者其他可行配置进行引入

<build>
    <resources>
        <resource>
            <directory>src/main/java</directory>
            <includes>
                <include>**/*.properties</include>
                <include>**/*.xml</include>
            </includes>
            <filtering>false</filtering>
        </resource>
    </resources>
</build>
