JFinal ActiveRecordPlugin插件事物交給Spring管理

最近在SpringBoot中使用JFinal的ActiveRecordPlugin插件窃躲，雖然事物可以直接通過(guò)@Before(Tx.class)來(lái)解決屯远，但是后面項(xiàng)目的需要將事物交給spring來(lái)管理，具體實(shí)現(xiàn)看下去

思路：使用spring AOP代理

這里使用springboot來(lái)實(shí)現(xiàn)昼丑，spring同理

maven 依賴

        <dependency><!-- spring boot aop starter依賴 -->
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-aop</artifactId>
        </dependency>
        <!-- 數(shù)據(jù)源 -->
        <dependency>
            <groupId>com.zaxxer</groupId>
            <artifactId>HikariCP</artifactId>
        </dependency>     
      其他的依賴直接省略了臭蚁，做程序的都知道的

感謝如夢(mèng)技術(shù)的代碼片段 , JFinal

    private TestService testService;

    @GetMapping(value = "/testTran")
    public Object testTran(){


        return testService.testTran();
    }
}

TestService

package com.choxsu.elastic.service;

import com.choxsu.elastic.config.JFinalTx;

    @JFinalTx
    public Object testTran() {
        Record record = new Record();
        record.set("id", 10);
        Db.save("test", record);
        if (true) {
            throw new RuntimeException("test");
        }
        return Ret.by("msg", "success");
    }
}

sql執(zhí)行了

Sql: insert into `test`(`id`) values(?)

但是數(shù)據(jù)庫(kù)沒(méi)有數(shù)據(jù)

到此證明事物攔截成功管跺，可以使用spring來(lái)管理ActiveRecordPlugin的事物了

去掉`throw new RuntimeException("test");`的效果

數(shù)據(jù)庫(kù)結(jié)果
