可以使用以下代码实现:
```
List<UserInfoVO> userList = page.getRecords();
List<String> passwords = new ArrayList<>();
for (UserInfoVO user : userList) {
passwords.add(user.getPassword());
user.setPassword(null); // 将密码设置为 null,防止密码被泄露
}
page.setRecords(userList);
```
首先,将原始的用户列表 `userList` 取出来,然后创建一个空的密码列表 `passwords`。接着,遍历 `userList`,将每个用户的密码加入到 `passwords` 列表中,同时将密码设置为 null,防止密码被泄露。最后,将处理后的 `userList` 设置回原始的 `page` 对象中。这样操作可以保护用户密码的安全性。

List<UserInfoVO> userList = page.getRecords();将 userList 中的 private String password放入 private String passwords中再将page.setRecords(userList);
可以使用以下代码实现:
```
List<UserInfoVO> userList = page.getRecords();
for (UserInfoVO user : userList) {
user.setPasswords(user.getPassword());
user.setPassword(null); // 将密码设置为 null,防止密码被泄露
}
page.setRecords(userList);
```
首先,将原始的用户列表 `userList` 取出来。接着,遍历 `userList`,将每个用户的密码赋值给 `passwords` 属性,同时将 `password` 属性设置为 null,防止密码被泄露。最后,将处理后的 `userList` 设置回原始的 `page` 对象中。这样操作可以保护用户密码的安全性。需要注意的是,需要在 `UserInfoVO` 类中添加 `private String passwords` 属性及其 getter/setter 方法。

从你提供的`server.xml`文件来看,`tomcat-users`元素是在`http://tomcat.apache.org/xml`命名空间下定义的,因此需要使用相应的命名空间前缀来引用该元素。
根据你的配置文件内容,将以下行:
```xml
<tomcat-users xmlns="http://tomcat.apache.org/xml"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://tomcat.apache.org/xml tomcat-users.xsd"
version="1.0">
```
修改为:
```xml
<tomcat-users xmlns="http://tomcat.apache.org/xml"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://tomcat.apache.org/xml tomcat-users.xsd"
version="1.0"
xmlns:ns2="http://tomcat.apache.org/xml">
```
然后,在以下行中添加命名空间前缀 `ns2`:
```xml
<role rolename="tomcat"/>
<role rolename="role1"/>
<user username="tomcat" password="tomcat" roles="tomcat"/>
<user username="both" password="tomcat" roles="tomcat,role1"/>
<user username="role1" password="tomcat" roles="role1"/>
```
修改为:
```xml
<ns2:role rolename="tomcat"/>
<ns2:role rolename="role1"/>
<ns2:user username="tomcat" password="tomcat" roles="tomcat"/>
<ns2:user username="both" password="tomcat" roles="tomcat,role1"/>
<ns2:user username="role1" password="tomcat" roles="role1"/>
```
这样修改后,`tomcat-users`元素及其子元素应该能被正确识别了。记得保存修改后的文件并重新启动Tomcat服务器。如果还有其他问题,请提供更多错误信息以便我能够帮助你进一步调试。
