1.前端頁面寫法

<a href="javascript:;" onclick="logoutBackground()">退出</a>

2.js

/**
 * 退出後臺
 */
function logoutBackground() {
    $.get("/admin/logout", function (msg) {
        if (msg === "true") {
            window.location.href = "/userlogin";//自定義靜態頁面路徑
        } else {
            alert("退出異常!");
        }
    });
}
 

3.security配置

 //登出操作
.logout().logoutUrl("/admin/logout")
.logoutSuccessHandler((request, response, authentication) -> {
　　PrintWriter writer = response.getWriter();
　　writer.write("true");
　　writer.close();
            }).permitAll()
