接下来,我们可以在需要限制字符串长度的地方使用@StringLengthLimit注解。下面是一个示例类User,其中使用了@StringLengthLimit注解来限制用户名和密码的长度: publicclassUser{@StringLengthLimit(minLength=1,maxLength=20)privateStringusername;@StringLengthLimit(maxLength=10)privateStringpassword;// 省略getter和setter方...
public String(byte bytes[], int offset, int length)可以看到，这里面的参数length是使用int类型定义...
&& ((String)var2).length >=65535) { this.log.error(var1,"limit.string",newObject[0]); ++this.nerrs; } } 代码中可以看出,当参数类型为String,并且长度大于等于65535的时候,就会导致编译失败。 这个地方大家可以尝试着debug一下javac的编译过程(视频中有对java的编译过程进行debug的方法),也可以发现这...
The length of field and method names, field and method descriptors, and other constant string values is limited to 65535 characters by the 16-bit unsigned length item of the CONSTANTUtf8info structure (§4.4.7). Note that the limit is on the number of bytes in the encoding and not on ...
