  @WebMvcTest + @AutoConfigureMockMvc,用 Boot 3 的包名
    [starter-test] 编译失败:package org.springframework.boot.test.autoconfigure.web.servlet does not exist | cannot find symbol
    [starter-webmvc-test] 编译失败:package org.springframework.boot.test.autoconfigure.web.servlet does not exist | cannot find symbol
    [starter-test-classic] 编译失败:package org.springframework.boot.test.autoconfigure.web.servlet does not exist | cannot find symbol
    [webmvc-test + data-jpa-test] 编译失败:package org.springframework.boot.test.autoconfigure.web.servlet does not exist | cannot find symbol
  @DataJpaTest,用 Boot 3 的包名
    [starter-test] 编译失败:package org.springframework.boot.test.autoconfigure.orm.jpa does not exist | cannot find symbol
    [starter-webmvc-test] 编译失败:package org.springframework.boot.test.autoconfigure.orm.jpa does not exist | cannot find symbol
    [starter-test-classic] 编译失败:package org.springframework.boot.test.autoconfigure.orm.jpa does not exist | cannot find symbol
    [webmvc-test + data-jpa-test] 编译失败:package org.springframework.boot.test.autoconfigure.orm.jpa does not exist | cannot find symbol

  @WebMvcTest + @AutoConfigureMockMvc,新包名
    [starter-test] 编译失败:package org.springframework.boot.webmvc.test.autoconfigure does not exist | cannot find symbol
    [starter-webmvc-test] @WebMvcTest 里 MockMvc 取到 hi  通过
    [starter-test-classic] (没有输出)  [失败: java.io.FileNotFoundException: class path resource [org/springframework/boot/security/autoconfigure/SecurityAutoConfiguration.class] cannot be opened because it does not exist]
    [webmvc-test + data-jpa-test] @WebMvcTest 里 MockMvc 取到 hi  通过
  @DataJpaTest,新包名
    [starter-test] 编译失败:package org.springframework.boot.data.jpa.test.autoconfigure does not exist | cannot find symbol
    [starter-webmvc-test] 编译失败:package org.springframework.boot.data.jpa.test.autoconfigure does not exist | cannot find symbol
    [starter-test-classic] @DataJpaTest 里保存后 count=1  通过
    [webmvc-test + data-jpa-test] @DataJpaTest 里保存后 count=1  通过
