Question

我正在使用Spring文档here。我的目标是使用＆＃34; webAppContextSetup＆＃34;选项以测试我的弹簧配置以及我的控制器，但是我无法将控制器的方法映射到TestDispatcherServlet内部。到目前为止，我有以下设置：

数据配置

    </bean>

    <bean id="transactionManager" class="org.springframework.orm.jpa.JpaTransactionManager"/>

    <context:property-placeholder location="classpath:config.properties"/>

</beans>

MVC配置

<?xml version="1.0" encoding="UTF-8"?>

       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

       xmlns:context="http://www.springframework.org/schema/context"

    <mvc:annotation-driven />

    <mvc:resources mapping="/public/**" location="/public/"/>

    <mvc:view-controller path="/" view-name="contract-management"/>

        <property name="prefix" value="/WEB-INF/"/>
        <property name="suffix" value=".jsp"/>
    </bean>
</beans>

ContractController.java

@RestController
@RequestMapping("contract")
public class ContractController {
    @Autowired
    DaoService daoService;

    @RequestMapping("{name}")
    public Contract getContract(@PathVariable String name) {
        return daoService.findContract(name);
    }
}

ContractControllerIT.java

@RunWith(SpringJUnit4ClassRunner.class)
@WebAppConfiguration
@ContextConfiguration("/spring/*.xml")
public class ContractControllerIT {
    @Autowired
    private WebApplicationContext webApplicationContext;

    private MockMvc mockMvc;

    @Before
    public void setup() {
        mockMvc = MockMvcBuilders.webAppContextSetup(webApplicationContext).build();
    }

    @Test
    public void getAccount() throws Exception {
        mockMvc.perform(get("contract/{name}", "test")).andExpect(status().isOk());
    }

}

目前，当我运行测试时，我看到以下错误：

java.lang.AssertionError: Status expected:<200> but was:<404>

有趣的是，在失败之前，一些看似矛盾的日志声明。

另外，这是我关于StackOverflow的第一个问题，所以关于如何改进我的问题的任何建议都是受欢迎和赞赏的。

最后一部分说明了一切：“合同/测试”没有映射，这是您在集成测试中执行GET请求的原因。

但是，控制器中的映射没有任何问题。唯一的问题是您在集成测试中省略了前导斜杠。

以下解决了您的问题：

@Test
public void getAccount() throws Exception {
    mockMvc.perform(get("/contract/{name}", "test"))
           .andExpect(status().isOk());
}

特别注意"/contract/{name}"中的前导斜杠。

我看到了一些不同于我通常为我的控制器做的事情。测试：

ContractController.java - 为两个请求映射添加斜杠：

@RequestMapping("/contract")
...
@RequestMapping("/{name}")

ContractControllerIT.java - 添加斜杠：

@Test
public void getAccount() throws Exception {
    mockMvc.perform(get("/contract/{name}", "test")).andExpect(status().isOk());
}

为什么我的Spring Controller的请求映射不能在模拟WebApplicationContext中工作？
