nutz版本低,没内置uuid函数吧

定位问题：实体类中存在一个uuid的，将uuid重命名即可

 @Name
    @Prev(els = @EL("uuid()"))
    @ColDefine(width = 32)
    private String id;

@Column("uuid")
    @ColDefine(width = 32)
    private String uuid;

版本

  <dependency>
            <groupId>org.nutz</groupId>
            <artifactId>nutz</artifactId>
            <version>1.r.61</version>
        </dependency>

哦.

应该用 org.nutz.lang.Lang.uuid() ?
