Kafka 生产者 自定义序列化

Kafka在生产者中序列化为二进制对象推送给Broker，下面是一个自定义序列化的示例，序列化一个User对象；

首先，引入jackson-mapper-asl

<dependency>
    <groupId>org.codehaus.jackson</groupId>
    <artifactId>jackson-mapper-asl</artifactId>
    <version>1.9.12</version>
</dependency>

然后定义需要被序列化的实体类：

package cn.org.fubin;

public class User {
    private String firstName;
    private String lastName;
    private int age;
    private String address;

    public User() {
    }

    public User(String firstName, String lastName, int age, String address) {
        this.firstName = firstName;
        this.lastName = lastName;
        this.age = age;
        this.address = address;
    }

    public String getFirstName() {
        return firstName;
    }

    public void setFirstName(String firstName) {
        this.firstName = firstName;
    }

    public String getLastName() {
        return lastName;
    }

    public void setLastName(String lastName) {
        this.lastName = lastName;
    }

    public int getAge() {
        return age;
    }

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

    public String getAddress() {
        return address;
    }

    public void setAddress(String address) {
        this.address = address;
    }

    @Override
    public String toString() {
        return "User{" +
                "firstName='" + firstName + '\'' +
                ", lastName='" + lastName + '\'' +
                ", age=" + age +
                ", address='" + address + '\'' +
                '}';
    }
}
