Spring 在视图中使用查找器

我不明白如何使用一个接受参数的finder只显示返回的数据。 例如，我在Principal entity中有一个finder

findPrincipalsByUsernameLike（String username）

，如何在

list.jspx

中使用该finder只显示用户的数据

Principle.java

@RooJavaBean
@RooToString
@RooJpaActiveRecord(table = "security_principals", finders = { "findPrincipalsByUsernameLike" })
public class Principal {

    @NotNull
    @Size(min = 5, max = 50)
    private String username;

    @NotNull
    @Size(min = 5, max = 50)
    private String password;


    private Boolean enabled;
}

users/list.jspx

<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<div xmlns:jsp="http://java.sun.com/JSP/Page"
    xmlns:page="urn:jsptagdir:/WEB-INF/tags/form"
    xmlns:table="urn:jsptagdir:/WEB-INF/tags/form/fields" version="2.0">
    <jsp:directive.page contentType="text/html;charset=UTF-8" />
    <jsp:output omit-xml-declaration="yes" />

    <page:find finderName="findPrincipalsByUsernameLike"
        id="ff_edu_gju_syria_model_security_principal"
        path="/principals/find">
        <input data-dojo-props="trim:true" data-dojo-type="dijit/form/TextBox"
            id="toolbarFilter" name="filter" type="text" value="${filter}" />
    </page:find>
    <page:list id="pl_edu_gju_syria_model_security_Principal"
        items="${principals}" z="+E0uiC5dOFGeuICZbYdoS6Nz80o=">
        <table:table data="${principals}"
            id="l_edu_gju_syria_model_security_Principal" path="/security/users"
            z="9ue3QOERNh44QuGQIg9JQzmFKnI=">
            <table:column id="c_edu_gju_syria_model_security_Principal_username"

        </table:table>
    </page:list>
</div>

如何在不向用户显示文本区域的情况下传递当前用户名？

您不必将用户作为请求参数发送

在处理请求的控制器方法中，只需从请求中获取用户主体
