-----测试类不能带参数

@Test
    public void getToken(这里面不能写参数)
    {
        String url = "https://api.weixin.qq.com/cgi-bin/token?grant_type=client_credential&appid=%s&secret=%s";
        String newUrl = String.format(url,"wxcafcded2fec9d8ad","5789ab99bb4887bb7ffe4fea39833476");
        TokenVO result = restTemplate.getForObject(newUrl, TokenVO.class);
        System.out.println(result.getAccess_token());
    }

2.java.lang.ExceptionInInitializerError

在使用springboot和Junit4进行整合的时候，进行单元测试的时候，出现 java.lang.ExceptionInInitializerError这个异常错误

是Junit的版本问题，pom.xml文件中改下版本就可以了

         <dependency>
            <groupId>junit</groupId>
            <artifactId>junit</artifactId>
            <version>4.11</version>
        </dependency>
把<version>4.11</version>改成<version>4.12</version>
