pom引入jar包

<dependencies>
        <dependency>
            <groupId>com.itextpdf</groupId>
            <artifactId>itextpdf</artifactId>
            <version>5.5.3</version>

先看效果  使用wps打开的  解决了不支持中文的问题--------网站上的HelloWorld不支持中文输出

 

整体项目   这里先说下 HelloWorld  下文解释所有

 

 //准备数据类

package com.wf.zhang.test;

public class Person {

    private String name;

    private Integer age;

    private String Adress;

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public Integer getAge() {
        return age;
    }

    public void setAge(Integer age) {
        this.age = age;
    }

    public String getAdress() {
        return Adress;
    }

    public void setAdress(String adress) {
        Adress = adress;
    }

    public Person() {
    }

    public Person(String name, Integer age, String adress) {
        super();
        this.name = name;
        this.age = age;
        Adress = adress;
    }

    @Override
    public String toString() {
        return String.format("Person [name=%s, age=%s, Adress=%s]", name, age, Adress);
    }

}
