通过Servlet跳转到jsp页面，jsp页面的样式不起效，但单独运行.jsp页面样式存在
老师您好，我的问题如下：
通过Servlet映射地址进入，跳转employee.jsp页面出现样式不存在
直接进入employee.jsp则样式存在
代码如下：Employee.java代码
package com.liu.util;
public class Employee {
private String eid;
private String ename;
private String department;
private String job;
private String salary;
public Employee(String eid,String ename,String department,String job,String salary){
this.eid=eid;
this.ename=ename;
this.department=department;
this.job=job;
this.salary=salary;
}
public String getEid() {
return eid;
}
public void setEid(String eid) {
this.eid = eid;
}
public String getEname() {
return ename;
}
public void setEname(String ename) {
this.ename = ename;
}
public String getDepartment() {
return department;
}
public void setDepartment(String department) {
this.department = department;
}
public String getJob() {
return job;
}
public void setJob(String job) {
this.job = job;
}
public String getSalary() {
return salary;
}
public void setSalary(String salary) {
this.salary = salary;
}
}

同学你好，如果是@WebServlet（"/employee/init"），访问路径中项目名后应该是employee/init。访问路径中有employee相当于是一个文件夹，再转发到其他的页面，应该是在这个文件夹下。同学在jsp页面中引入其他的文件时，路径中是不包含这个employee文件夹的，所以引入文件404.
如果我的回答解决了你的疑惑，请采纳。祝：学习愉快~
