In this section, let us learn 3 ways to use sisyphus together.

sisyphus proxy template

Purpose

In order to facilitate users to use annotations more conveniently, without relying on spring at the same time.

Provides implementation based on code mode + bytecode enhancement.

Use Cases

Introduced by maven

Introduce annotation related modules.

<dependency>
    <groupId>com.github.houbb</groupId>
    <artifactId>sisyphus-annotation</artifactId>
    <version>0.0.9</version>
</dependency>

Define the test method

The following test code can refer to the [spring-test]() module.

• MenuServiceImpl.java

public class MenuServiceImpl {

    public void queryMenu(long id) {
        System.out.println("查询菜单...");
        throw new RuntimeException();
    }

    @Retry
    public void queryMenuRetry(long id) {
        System.out.println("查询菜单...");
        throw new RuntimeException();
    }

}

test

Use RetryTemplate for testing

Method without retry annotation

@Test(expected = RuntimeException.class)
public void templateTest() {
    MenuServiceImpl menuService = RetryTemplate.getProxyObject(new MenuServiceImpl());
    menuService.queryMenu(1);
}

• Log information

查询菜单...

Only requested once.

Annotated method

@Test(expected = RuntimeException.class)
public void templateRetryTest() {
    MenuServiceImpl menuService = RetryTemplate.getProxyObject(new MenuServiceImpl());
    menuService.queryMenuRetry(1);
}

• Log information

查询菜单...
查询菜单...
查询菜单...

sisyphus spring integration

Purpose

Similar to the spring-retry framework, if you use the spring framework, the integration of this project will be very simple.

The way of annotation and procedural programming, the two are as consistent as possible, and it is relatively simple for you to change from one way to the other.

It is also very convenient to switch from spring-retry to this framework.

Introduced by maven

<dependency>
    <groupId>${project.groupId}</groupId>
    <artifactId>sisyphus-spring</artifactId>
    <version>${project.version}</version>
</dependency>

Spring and AOP related jars will be introduced by default.

Business code

You can refer to the sisyphus-test module.

Some very common business methods are simulated below.

Using the @Retry identification method requires a retry.

• SpringService.java

public interface SpringService {

    /**
     * 查询示例代码
     * @return 结果
     */
    String query();

}

• SpringServiceImpl.java

import com.github.houbb.sisyphus.annotation.annotation.Retry;
import com.github.houbb.sisyphus.test.service.SpringService;
import org.springframework.stereotype.Service;

/**
 * @author binbin.hou
 * @since 0.0.4
 */
@Service
public class SpringServiceImpl implements SpringService {

    @Override
    @Retry
    public String query() {
        System.out.println("spring service query...");
        throw new RuntimeException();
    }

}

Turn on retry

Simply configure as follows based on the annotations.

Using the @EnableRetry flag requires retrying.

@Configurable
@ComponentScan(basePackages = "com.github.houbb.sisyphus.test.service")
@EnableRetry
public class SpringConfig {
}

Test code

import com.github.houbb.sisyphus.test.config.SpringConfig;
import com.github.houbb.sisyphus.test.service.SpringService;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;

/**
 * @author binbin.hou
 * @since 0.0.4
 */
@ContextConfiguration(classes = SpringConfig.class)
@RunWith(SpringJUnit4ClassRunner.class)
public class SpringServiceTest {

    @Autowired
    private SpringService springService;

    @Test(expected = RuntimeException.class)
    public void queryTest() {
        springService.query();
    }

}

• Log information

spring service query...
spring service query...
spring service query...

sisyphus springboot integration

Purpose

Similar to the spring-retry framework, if you use the springboot framework, the integration of this project will be very simple.

The way of annotation and procedural programming, the two are as consistent as possible, and it is relatively simple for you to change from one way to the other.

It is also very convenient to switch from spring-retry to this framework.

The overall integration is similar to spring, and it is simpler.

Introduced by maven

<dependency>
    <groupId>${project.groupId}</groupId>
    <artifactId>sisyphus-springboot-starter</artifactId>
    <version>${project.version}</version>
</dependency>

Springboot integration related dependencies will be introduced by default.

Business code

You can refer to the sisyphus-test springboot test module.

Some very common business methods are simulated below.

Using the @Retry identification method requires a retry.

• SpringService.java

public interface SpringService {

    /**
     * 查询示例代码
     * @return 结果
     */
    String query();

}

• SpringServiceImpl.java

import com.github.houbb.sisyphus.annotation.annotation.Retry;
import com.github.houbb.sisyphus.test.service.SpringService;
import org.springframework.stereotype.Service;

/**
 * @author binbin.hou
 * @since 0.0.4
 */
@Service
public class SpringServiceImpl implements SpringService {

    @Override
    @Retry
    public String query() {
        System.out.println("spring service query...");
        throw new RuntimeException();
    }

}

Test code

• SisyphusApplicationTest.java

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(classes = SisyphusApplication.class)
public class SisyphusApplicationTest {

    @Autowired
    private SpringService springService;

    @Test(expected = RuntimeException.class)
    public void queryTest() {
        springService.query();
    }

}

The code of SisyphusApplication.java is as follows:

It is the most basic springboot start entry.

@SpringBootApplication
@ComponentScan(basePackages = "com.github.houbb.sisyphus.test.service")
public class SisyphusApplication {

    public static void main(String[] args) {
        SpringApplication.run(SisyphusApplication.class, args);
    }

}

• Log information

spring service query...
spring service query...
spring service query...

summary

The three usage methods can basically meet various scenarios in daily development.
