#long 转string
long a =1l;
log.info("long类型转换String: {}",String.valueOf(a));string 转long
long l = Long.valueOf("123").longValue();#boolean 转string
boolean a = true;
log.info("boolean类型转换String: {}",String.valueOf(a));#int转string
int a = 1;
log.info("int类型转换String: {}",String.valueOf(a));
或者
log.info("int类型转换String: {}", a+"");String转为int
int i=Integer.parseInt（string）;
或者
int i=Integer.valueOf(s).intValue();
