不兼容的类型错误将在升级为5.3.20之后显示
全部， 我有一个Junits的Maven Java项目： 例如：
import static org.springframework.test.web.servlet.result.MockMvcResultMatchers.jsonPath;
import com.jayway.jsonassert.impl.matcher.IsCollectionWithSize;
@Test
public void test() throws Exception {
getMockMvc().perform(put("/bla")
.contentType(MediaType.APPLICATION_JSON_VALUE)
.accept(MediaType.APPLICATION_JSON_VALUE)
.characterEncoding("UTF-8")
.content("{\n" +
"\n" +
"\"eventTypes\": [\"BLA\"]\n" +
"\n" +
"}"))
.andExpect(jsonPath("$.eventTypes", IsCollectionWithSize.hasSize(1)));
}
运行检查的行： JSONPATH（“ $。EventTypes”，IscollectionWithSize.Hassize（1）
JSONPATH是Spring Libary Verion 4.3.30的一部分 isCollectionWithSize.hassize是com.jayway.jsonpath.json-path-assert verion 2.4
一切正常的，直到我将春季升级到5.3.20，一切正常 错误是：
incompatible types: cannot infer type-variable(s) T,capture#79 of ? super java.util.Collection<? extends E>,E
[ERROR] (argument mismatch; org.hamcrest.Matcher<capture#80 of ? super java.util.Collection<? extends E>> cannot be converted to org.hamcrest.Matcher<? super java.lang.Object>)
[ERROR] -> [Help 1]
有人有这样的问题吗？可以提供解决方案吗？
all,
I have a maven java project with junits:
for example:
import static org.springframework.test.web.servlet.result.MockMvcResultMatchers.jsonPath;
import com.jayway.jsonassert.impl.matcher.IsCollectionWithSize;
@Test
public void test() throws Exception {
getMockMvc().perform(put("/bla")
.contentType(MediaType.APPLICATION_JSON_VALUE)
.accept(MediaType.APPLICATION_JSON_VALUE)
.characterEncoding("UTF-8")
.content("{\n" +
"\n" +
"\"eventTypes\": [\"BLA\"]\n" +
"\n" +
"}"))
.andExpect(jsonPath("$.eventTypes", IsCollectionWithSize.hasSize(1)));
}
the line that run the check:
jsonPath("$.eventTypes", IsCollectionWithSize.hasSize(1)
the jsonPath is part of Spring libary verion 4.3.30
and the IsCollectionWithSize.hasSize is taken form com.jayway.jsonpath.json-path-assert verion 2.4
everything worked ok until I upgraded the Spring to 5.3.20
The error is:
incompatible types: cannot infer type-variable(s) T,capture#79 of ? super java.util.Collection<? extends E>,E
[ERROR] (argument mismatch; org.hamcrest.Matcher<capture#80 of ? super java.util.Collection<? extends E>> cannot be converted to org.hamcrest.Matcher<? super java.lang.Object>)
[ERROR] -> [Help 1]
Has anyone had such a problem? And can offer a solution?

好的，我通过更改其中一个进口来修复它。
而不是这样：
我使用了以下方式：
并从中更改代码：
对此：
ok so I fixed it by changing one of the imports.
instead of this:
I used this:
and change the code from this:
to this:
