JSON

jsON

HTML控制台显示

jsp 显示JSON

1.通过attribute 只能是jsp，如果是html ，html不支持java代码，不能直接传对象

@WebServlet("/jsonServlet")public class JsonServlet extends HttpServlet { @Override protected void doGet(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException { Student student = new Student(); student.setId(1); student.setAge(19); student.setName("小明"); req.setAttribute("student",student); req.getRequestDispatcher("/index.jsp").forward(req,resp); }

2.通过 resp 写入json@WebServlet("/jsonServlet")public class JsonServlet extends HttpServlet { @Override protected void doGet(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException { Student student = new Student(); student.setId(1); student.setAge(19); student.setName("小明"); resp.setContentType("text/html;charset=UTF-8"); resp.setCharacterEncoding("UTF-8"); resp.getWriter().print(new Gson().toJson(student)); }这个需要google gson-2.5.jar（谷歌）

public class Student { private int id; private String name; private int age; private String sex; private float height; private Date birthday; public int getId() { return id; } public void setId(int id) { this.id = id; } public String getName() { return name; } public void setName(String name) { this.name = name; } public int getAge() { return age; } public void setAge(int age) { this.age = age; } public String getSex() { return sex; } public void setSex(String sex) { this.sex = sex; } public float getHeight() { return height; } public void setHeight(float height) { this.height = height; } public Date getBirthday() { return birthday; } public void setBirthday(Date birthday) { this.birthday = birthday; } @Override public String toString() { return "Student{" + "id=" + id + ", name='" + name + '\'' + ", age=" + age + ", sex='" + sex + '\'' + ", weight=" + height + ", birthday='" + birthday + '\'' + '}'; }}
