Dependencies

maven

http://130.10.8.208/repository/bksx-maven/

    <dependency>
        <groupId>com.sx</groupId>
        <artifactId>bksx-redis</artifactId>
        <version>v0.9.1.20170531</version>
    </dependency>

Init

读取配置,构建RedisConfig配置对象。如下为示例代码，实际项目中根据实际配置文件读取方法进行构建。

private RedisConfig getConfig(){
    RedisConfig rc = new RedisConfig();
    Map<String, String> map = new HashMap<>();
    map.put("host","130.10.7.243");
    map.put("port","6379");
    Map<String, String> map1 = new HashMap<>();
    map1.put("host","130.10.7.244");
    map1.put("port","6379");
    Map<String, String> map2 = new HashMap<>();
    map2.put("host","130.10.7.245");
    map2.put("port","6379");
    List<Map<String,String>> list = new ArrayList<>();
    list.add(map);//单个redis实例配置一个ip端口map，redis集群时配置多个
    list.add(map1);
    list.add(map2);
    rc.setRedis(list);
    return rc;
}

调用初始化方法

SxRedis.init(getConfig());//参数为读取的配置信息

Test

SxRedis.set("foo","bar");
System.out.println("get foo from redis ,value is " + 
    SxRedis.get("foo"));

测试输出

get foo from redis ,value is bar

对象操作

class User implements Serializable{
    private static final long serialVersionUID = 1L;
    private String name;
    private int age;
    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;
    }
    @Override
    public String toString() {
        return "User{" +
                "name='" + name + '\'' +
                ", age=" + age +
                '}';
    }
}

User user = new User();
user.setAge(22);
user.setName("red");
SxRedis.set("user".getBytes(), SerializeUtil.serialize(user));
user = SerializeUtil.unserialize(SxRedis.get("user".getBytes()));
System.out.println(user);

测试输出

User{name='red', age=22}

其他使用方法请参考SxRedis javadoc。现提供方法为常用方法，如果需要其他方法可将方法需求提交组长，评估后统一添加

公司开发环境

配置：

Host	Port
130.10.7.243	6379
130.10.7.244	6379
130.10.7.245	6379

规定：使用redis时key必须以"项目名-"开头。

e.g.
set rbac-foo bar
set bjsjzz-user-15212345678 red

Update

add keys method

version

    <dependency>
        <groupId>com.sx</groupId>
        <artifactId>bksx-redis</artifactId>
        <version>0.9.2.v20170619</version>
    </dependency>

test code

IntStream.range(1,10).forEach(key->{
    SxRedis.set("test-prefix-"+key,key+"");
});

TreeSet<String> keys = SxRedis.keys("test-prefix-*");
keys.stream().forEach(System.out::println);

test print

test-prefix-1
test-prefix-2
test-prefix-3
test-prefix-4
test-prefix-5
test-prefix-6
test-prefix-7
test-prefix-8
test-prefix-9
