创建mockMvc，增加filter。

private MockMvc mockMvc;
    @BeforeEach
    void before(WebApplicationContext context) {
        mockMvc = MockMvcBuilders.webAppContextSetup(context)
                .addFilter((request, response, chain) -> {
                    response.setCharacterEncoding("UTF-8");
                    chain.doFilter(request, response);
                }, "/*")
                .build();
    }
