Struts2+hibernate3.3+Spring
SysUserConfig sysUserConfig = 
this.sysUserConfigService.getSysUserConfig(this.sysUserConfig.getId());

out.write(new GsonBuilder().setDateFormat("yyyy-MM-
dd").disableHtmlEscaping().create().toJson(sysUserConfig));

output:

This doesn't look like a defect. Using GsonBuilder, you can specify to only 
serialize
objects which match the @Expose annotation, or you could build a proxy class 
with
only those fields, set them from sysUserConfig, and then serialize that.
