下面的代码是give:user/userresources/userservice我写的：schritt3.java
我得写一个测试，但我完全迷路了。我在google上搜索了那么多，没有找到解决办法。
第一次尝试´s此错误：resteasy003320:处理public java.util.list de.hse.swa.jaxquarkus.step3.userresource.adduser的参数失败（java.lang.string，java.lang.string，java.lang.string，java.lang.boolean）
第二个打开：预期状态代码<200>，但为<400>。
如您所见，我尝试了不同的编码类型和方法来解析数据。但是谷歌搜索错误信息对我一点帮助都没有。我不知道´我不知道我是不是走错了路，还是有什么不对劲。
所以问题是：如何正确传递数据。
